Jeffrey Johnson
A. Ronald Gallant Distinguished Professor; Department Chair
On Mother’s Day I had the privilege of giving the commencement address to an exceptional cohort of newly minted degree recipients at the Department of Chemistry’s commencement exercises. The very loose title of the talk was “And One.” If there happen to be any basketball fans (!) and/or former denizens of Wollen Gymnasium among the readership, you will immediately recognize the phrase to describe the event when a shooter is fouled, makes the shot, and is awarded a free throw, the latter being the ‘and one.’ Fundamentally, the ‘and one’ is a reward for being tough. The ‘And One’ of May’s commencement talk began, but did not end with where we found ourselves in the department’s history. Many of you are aware that the UNC Department of Chemistry was founded in 1818 and last year the department celebrated its bicentennial. In April 2018 we welcomed over 300 alumni and friends back to Chapel Hill to share the history and stories and successes of Carolina Chemistry. Much of what I wrote about last year focused on the rich history of the department. So what is the connection to the notion of ‘And One’? Celebrations and milestones are important, critically so. They can represent culminations and achievements and longevity, strength and accomplishment. But milestones are very seldom the end of the journey, but rather a pause – we are metaphorically pulling off the highway to view a spectacular yet ephemeral sunset. The department celebrating its bicentennial allowed us to pause and reflect on our staying power, our advances, our amazing people…but the march to year 201 was ineluctable, inevitable, and necessary. The department’s history moves on; the past is critically important, but we live in the present and have to embrace the opportunity and uncertainty in shaping our future. Two hundred ‘and one’, or n+1, is always coming. The entropy of a system is increasing. For our graduating seniors considering their ‘system,’ their disorder was about to take a step function up. Life very seldom looks more complex, or can even be conceived of being more complex or disordered than the moment you currently inhabit. Your high school self could scarcely conceive of how simple things were for your middle school self, while the college graduate chuckContinued on page 19 CHEM.UNC.EDU | CHEMISTRY AT THE UNIVERSITY OF NORTH CAROLINA | 3

Why I Give It was the year 1992 - it was summer. Not only had I completed my undergraduate degree in chemistry at the University of North Carolina-Greensboro, but had also married Sharon, now my wife for twenty-seven years. It was a wonderful summer.
My undergraduate Professors Terry Nile and Jim Barborak had conChris Killian, Ph.D. vinced me to pursue my Ph.D. in chemistry, and to do so at UNC-Chapel Hill. I was wide eyed and a bit apprehensive in thinking on what my upcoming graduate school experience would have in store for me. Little did I know, that the next four years would change the trajectory of my professional life in ways I could not imagine at the time. During my first year at Carolina Chemistry, I was challenged and inspired by professors Templeton, DeSimone, Evans, and Brookhart. The academic course work was intense and challenging, but also brought with it the broader Carolina experience and a lot of new friends. Being a newlywed made my time at Carolina Chemistry one of the best experiences of my life. Spring semester of my first year, I was invited to join Professor Maurice Brookhart’s research group to work on Ni and Pd catalyst for olefin polymerization. Professor Brookhart epitomizes the collegial nature and spirit of the UNC Department of Chemistry. He is a first-class human being of high character, a great teacher, mentor and advisor. He often invited his group up to Franklin Street for food and fellowship. We also spent many evenings at his home enjoying his and his wife Mary Hughes’ hospitality. Brook challenged us all to develop a first principles understanding of the research we were pursuing–a principle I have instilled in the teams that I have led in my twenty years of leading R&D organizations. Professor Joe DeSimone also had a tremendous impact on my academic and professional development. The nature of my research had both a heavy organometallic component and a heavy polymer component, leading me to become an adopted member of the DeSimone group.
Joe was an incredible mentor and teacher. I began to shape my leadership style and professional ambitions through weekly engagements with him. He took a special interest in me and my work, which I appreciate to this day. My research opened many doors, including an industrial collaboration with DuPont and many speaking engagements. Upon graduation, I knew I wanted to go into industry, do research for a period and then grow into technology/R&D management. Shortly after my defense and graduation, I took a position with Eastman in 1996, after considering offers from several global chemical and materials companies. My time in the UNC Department of Chemistry prepared me well for my career at Eastman and for a life-long journey of personal/professional growth and development. I have had the chance to lead teams in the commercialization of dozens of new products, including Eastman Tritan™ copolyester, new to the world engineering plastic, and Visualize Material™ 500, used in compensation films for smart phones. I am currently Vice President of Technology for two of Eastman’s four reporting business segments. Sharon and I have given back to the department in many ways over the years, including regular financial contributions and through my participation on the Chemistry Advisory Board. Very recently, Sharon and I have chosen to have a long-term strategic impact on the quality of the graduate student experience through the creation of an endowed fund for supporting graduate students in the department. This was an easy choice for Sharon and me to make, as I can say with confidence that my time at UNC and the relationships I built have been instrumental to the accomplishments I have been blessed to be a part of. I hope that the current and future graduate students of the UNC Department of Chemistry experience the blessings of growth, personal/professional development, and accomplishment that I did.

Advancing Undergraduate Chemistry Education at UNC Chapel Hill by Re-envisioning the Modern Chemistry Teaching Laboratory Nita Eskew, Ph.D., Director, Undergraduate Laboratories Chances are high if you are reading this article and graduated within the past 30 years, you have a story to tell about time you spent in Morehead Labs. Each year, over 5,000 UNC undergraduates take laboratory courses in the same building and gain meaningful training in laboratory and research skills. For over three decades, Morehead Labs has been serving students from across the university over a broad range of majors and backgrounds. While its walls stand unchanged, the nature of chemistry pedagogy to best train and educate students in STEM has evolved significantly. If we are to maintain our leadership in undergraduate STEM education, the spaces within Morehead Labs must be re-imagined and subsequently renovated to meet the demands of the modern chemistry teaching curriculum. As a foundational discipline, chemistry is by definition convergent, cross-cutting, and collaborative. The future chemistry professional will need to be trained to work and communicate within multidisciplinary teams. Traditional chemistry lab modules that pair students together to take turns running the same experiment is foundational, but modern chemistry demands that we do more.
We have invested heavily, but opportunities for giving are numerous. Our goal is to transform every laboratory in Morehead within the next decade. Your gifts have a direct and tangible impact on our department. We hope you will consider joining our effort to transform undergraduate Chemistry at Carolina for tens of thousands of students.
The ideal teaching lab will bring pairs into collaborative teams of students around a designated space with the ability to work on meaningful research problems and share their results both within and between teams. Ventilation stations dedicated to each student pair will remain an invaluable resource, enabling students to safely conduct rigorous experiments that wouldn’t otherwise be possible. The design of a pilot laboratory that embodies each of these features is well underway. Graphic renderings are shown in the accompanying figures. Thanks to generous support from the Dean of the College of Arts and Sciences and the Department of Chemistry, we have raised the $1.5 M required to begin construction in the Summer of 2020 to transform two labs into Labs of the Future.

Cyclic Voltammetry
Bootcamp This Cyclic Voltammetry Bootcamp was designed to provide students with the opportunity to learn the basics of cyclic voltammetry without taking a formal class. The two-day workshop allowed 17 participants from all different backgrounds to gain the practical skills necessary to utilize cyclic voltammetry and other basic electroanalytical techniques in their own research. During the workshop, students were introduced to both theoretical and practical aspects of electrochemistry through lectures.
gave them the opportunity observe the differences in signal between a large electrode and a very small electrode. Ultimately, the goal of the workshop was to equip students from several different backgrounds with the tools necessary to design electroanalytical experiments, carry out experiments, troubleshoot common problems, and analyze the data that was generated.
With eight electrochemical workstations lent by Pine Research Instrumentation, students were given an opportunity to go into the lab and get their hands wet with three different experiments. One lab was devised to force students to troubleshoot common problems, and another
!
This workshop was enabled by support from the Department of Chemistry ‘Say Yes Fund,’ equipment and instructional support from Pine Research Instrumentation, and the graduate student teaching assistants from the Jeffrey Dick and Jillian Dempsey labs who helped develop, test, and supervise the lab activities.

From the Dean Earlier this fall, I visited Carolina Chemistry as part of a “listening and learning tour” that I embarked on after being appointed interim dean of the College of Arts & Sciences in February. I have been part of the dean’s office since 2012, serving for seven years as senior associate dean for fine arts and humanities, but it was important for me to have firsthand knowledge about the research activity of our faculty in the natural sciences and mathematics. I was deeply impressed by the research and innovation that is happening in that department. It is no surprise that Carolina Chemistry is one of top-ranked programs in the nation. Working in solar and thermal energy, nanomedicine, polymer science, mass spectrometry and other areas, our chemistry faculty are leading the way in defining solutions for some of the major challenges of our time. Students and faculty are also teaming up with colleagues in other disciplines to tap into the power of interdisciplinary problem-solving. This culture of collaboration and outside-the-box thinking is what we mean by the College of Arts & Sciences’ tag line: Synergy Unleashed. Carolina Chemistry faculty are also extraordinary instructors and mentors for our undergraduate and graduate students, regularly winning awards for their teaching. They are preparing our students to become the innovators and scientist-entrepreneurs of tomorrow. I look forward to 2020 being another year of Carolina Chemistry innovation and accomplishment.

Stress could be considered synonymous with chemistry graduate school. A first year student faces challenging courses, teaching assistantships, grading assignments, and navigating the path to a doctoral advisor and research group — all while acclimatizing to life in a new place. Later in the PhD program, students venture into new and uncharted research areas where frequent failure is commonplace. Postdoctoral scholars face a short timeline to learn new skills and make discoveries that will propel them to permanent employment. But what is the toll of such stress? A 2017 mental health and wellness survey of UNC Chapel Hill students found that 60% of graduate students felt overwhelming anxiety and 31% felt so depressed that it was difficult to function. We believe that the department can help graduate students and postdocs reach their full potential by building an environment with multiple layers of support. The need for an improved departmental climate was underscored by a 2018 climate survey led by graduate students in the department. The high (70%) response rate itself highlights an engaged community eager to improve itself. While there were positive signs, a significant fraction of students felt isolated in the department for personal or professional reasons. Others had experienced
conflicts or disagreements with peers of faculty. Few acted to address these challenges. In response to national and local trends, the Department has founded the Student and Postdoc Wellness Committee, SWELL, with a mission to foster a healthy and vibrant graduate student & postdoc community. SWELL is comprised of 8 faculty and staff, led by cochairs Leslie Hicks and Alex Miller. The committee has representation from teaching and research faculty from various disciplines and staff from the teaching laboratories and student services. Many in this diverse group have completed formal trainings including Safe Zone, Mental Health First Aid, and Haven. The committee will play several roles, including advising on disagreements/conflicts, health issues, or any other concerns; organizing community-building activities within the department; and curating and distributing information about campus resources pertaining to mental health and general wellness. In the 2019-2020 academic year, SWELL is focused on several major initiatives. A new SWELL Website provides a centralized and curated information on resources, reporting, training opportunities. A new graduate student and postdoc lounge was completely renovated and had its grand opening in October on the first floor of Kenan Labs. The framework of a peer mentoring network is being built for launch in 2020, with senior graduate students paired with first years upon arrival. The SWELL Committee holds two weekly office hours where students and postdocs can find a supportive place for discussions. The committee will also partner with other campus entities to ensure low-barrier access to professional mental health and wellness resources.

Graduate Committee for Professional Development
One of the findings of the recent Department Climate Survey was the need to further foster professional development, especially when it came to non-faculty career paths.
As a response to this, the Graduate Committee for Professional Development, GCPD, pictured above, was created in January of 2019 to define and execute a department wide plan to prepare and educate students and postdocs about potential career paths available to chemistry Ph.D.s. Since their inception the committee has hosted several workshops and information sessions, such as “Plotting a Career Timeline” and “Business Certificates Available to Graduate Students”. In addition they have created a seminar series, “Career Answers for Chemists”, that brings in professionals from different disciplines, from working at a chemical company like BASF, to working in science policy in DC, and has them share their stories and tips on how to plot an exciting career path. Keep an eye out for GCPD in 2020 as these talented individuals draw on the successes from prior events to bring in more speakers from out of town. They are also planning to host a full day career development conference for senior students that aims to bring in industry professionals for intimate networking and accelerated professional development.

The Wilkerso The Hill group is yet another new group at Carolina Chemistry. Members in this laboratory strive to develop new enantioselective reaction methodology in order to synthesize complex molecules with important biological function. This research merges Assistant Professor Sidney Wilkerson-Hill’s training in synthetic organic chemistry and enantioselective catalysis, to address unsolved problems in synthesis with the long-term goal to provide new non-invasive tools for studying the living human brain, using positron emission tomography, PET. With these methods the group members will advance the knowledge of chemical reactivity in complex environments and provide new knowledge about how the central nervous system, CNS, functions. Specifically, the group members are interested in developing new biomimetic cyclopropanation reactions using 1) frustrated Lewis acid-base pairs, FLP’s, 2) ketenes, bisketenes, and their equivalent compounds, and 3) asymmetric functionalization reactions of pyridines.
Natural Products
Isolated from plants, bacteria, marine sponges and other natural sources, complex secondary metabolites, natural products, often have important biological function, for example, active in the central nervous system, anti-HIV, anticancer. As such, this chemical matter provides a unique starting point for the development of

on-Hill Group new pharmaceuticals. Additionally, these compounds are often used as tools for understanding biology, and their complex architectures are well-suited for investigating molecular reactivity in complex chemical environments.
A major thrust in the Hill lab focuses on using natural products as tools for understanding complex biology. Group members are currently trying to access plagiochianin B, a pyridine-containing ent-2,3,-seco-aromadendrane derivative reported in 2018. The lab members are excited about this molecule due its relationship to plagiochilal B, a small molecule isolated in 1991 from Plagiochila fruticosa. Plagiochilal B was reported to enhance choline acetyltransferase activity in rat cerebral hemisphere, which may make it an important molecule for studying Alzheimer’s disease. Continued on page 24

Sustainability
At the department’s annual “State of the Department” address, Professor and Chair Jeff Johnson asked “What is the department doing to be sustainable?” Inspired by this question, the department formed a new Sustainability Committee in August to guide and inform our efforts to become more sustainable. The committee is comprised of faculty, staff, graduate students, and post-docs from across the department. Since its inception, the committee has been working towards improving sustainability practices on both small and large scales within the department, and collaborating with groups in Chemistry and across campus. One project involves collaborating with the UNC Office of Waste Reduction and Recycling, and UNC Green Labs, to educate the department members on UNC’s recycling policies with the goal of increasing recycling participation across the department.
Pictured, from left to right: Nicole Parsley, Lauren McRae, Jessica Coleman, Marcey Waters, Kelsey Kean, Hannah Ferguson Johns, Katherine Albanese, Emilia Leon, and Mandy Melton. Not pictured from the Sustainability Committee: Tyler Motley, Ian VonWald, and Randy Simmons
Following the lead of our teaching labs, research labs are now widely participating in nitrile lab glove recycling through VWR. Additionally, the department is participating in a pilot program with Thermo Fisher Scientific to recycle plastic films. Along with the Social Activities Committee, the committee works to make department-wide events greener, with a focus on reducing waste and using compostable or reusable items whenever possible. For the future, the committee has set their sights on establishing composting across the department, providing recommendations for sustainable practices in the laboratory, and ultimately working towards having solar panels in use across the chemistry building complex. In a big department like ours, even taking these small steps towards reducing, reusing, and recycling are making a huge impact!

les conspiratorially at its 18-year-old predecessor, wondering how he or she had it quite so easy. The assistant professor dreams of inventing the 25th and 26th hour of the day, while the department chair looks longingly at his or her 30-year-old version who only had to worry about teaching and research and service. To our graduates, I conveyed that even with my limited wisdom I could confidently share that there are two ways one can meet the inevitable march of rising entropy. The first is to struggle, fret, and worry over the demands, the deadlines, all the “adult” stuff; however, it’s called a law of thermodynamics for a reason. So I recommended a second course of action, which is to embrace the disorder and look at it as the challenge and opportunity that it is. The world one enters as a B.S. or B.A. or Ph.D. graduate is undeniably entropic, messy and complex, but I would contend that it is those very characteristics that are nearly custom built to allow us to assert our vision and make an impact. However, it means accepting that life gets more complex as we go, and that is probably a good thing. The march in “year 201” continues unabated. We welcomed three new faculty colleagues to our ranks in July, with the arrival of Professors Zhiyue Lu, Alex Zhukovitskiy, and Anna Curtis. The department has commenced a new student wellness initiative, SWELL, and its launch coincides with the complete upgrade and renovation of the graduate student lounge. Professors Jillian Dempsey and Jeffrey Dick launched a Cyclic Voltammetry Boot Camp. Professor Frank Leibfarth was recognized as a Beckman Young Investigator and as one of Chemical and Engineering News’s ‘Talented 12,’ while Professor Leslie Hicks rang the awards bell multiple times, having been selected by Iota Sigma PI, the National Honorary Society for Women in Chemistry, to receive the 2019 Agnes Fay Morgan Research Award, by the ACS Women Chemists Committee as a 2020 Rising Star Awardee, and by Marshall University for the Distinguished Alumni Award. Emeritus Professor Tom Baer was celebrated by former
co-workers with a symposium on the occasion of his 80th birthday, while alumni of Professor Jim Jorgenson’s group returned to Chapel Hill in May to fête Jim on the occasion of his retirement from the university, recognizing a remarkable career filled with scientific excellence. These are but small vignettes in the vibrant 201st year of the department. I invite you to explore the pages of this missive to learn more about what is happening here at UNC Chemistry. Finally, I would like to share that my term as the department chairperson ends on June 30, 2020. It has been an honor to lead such an impressive group of people. There will be a local decrease in entropy associated with this particular member of the faculty, but I feel confident that global disorder will continue to obey all the relevant thermodynamic laws, and that the department will continue to embrace the opportunities that circumstance presents. As always, we welcome visitors to the department and I extend an open invitation if you find yourself in Chapel Hill. Of course, I am wishing all of our Carolina Chemistry community a very prosperous and happy 2020.

Reaction Methodology
The development of new reactions is critical for advances in many fields such as pharmaceutical, biological, and material sciences, because doing so permits access to unique chemical space. Structurally complex dimeric products represent unique chemical space, because reactions that allow cross dimerization reactivity are lacking.
Linchpin strategies are a nontraditional take on dimeric components and provide the advantage of being convergent and opportunities to access dimers that lack bilateral symmetry. In the Hill lab, members have developed a new linchpin reagent bis(2-chloroacrylonitrile) and are currently investigating its reactivity and ability to provide dimeric natural products which contain, or lack, bilateral symmetry.
Total Synthesis
The sequence of reactions by which a complex natural product is obtained is of paramount importance. Unique synthetic strategies can result in the development of innovative reaction methodologies, uncover new reactivity of small molecules, and begin to address shortages natural compounds used as leads for drug development. Total synthesis also provides a means to confirm the structure of natural products, which can be critical for understanding how they function.

The Hill lab members are excited about developing new cyclopropanation strategies to access complex molecules. Specifically, they have begun to access the core fragment of cerorubinic acid III. This complex molecule facilitates insect communication, and to our knowledge is the most complex known to do so. Interestingly, the core structure of this compound resembles that of a class of anticancer compounds discovered here in the research triangle, paclitaxel, so building these molecules could provide derivatives with unique anticancer activities. Consequently, we are developing a new cyclopropanation strategy to do so which makes use of unconventional carbene precursors.
Outreach and Service
As a native of Kinston, NC, outreach and making an impact on the broader community has always been important to Professor Wilkerson-Hill. During his research experiences, he has also discovered that science is a subject with the power to address, if not drastically change, socioeconomic situations by the inherent virtues that this subject instills, curiosity, critical thinking, teamwork, et cetera. Consequently, Dr. Wilkerson-Hill’s future role as a research scientist is not only to produce great science that will have greater impacts on the global community, but to help produce great scientists who will do the same, while simultaneously fostering curiosity and a sincere appreciation for the sciences in the general public. To accomplish this, Professor Wilkerson-Hill has developed and participated in programs that promote science and diversity on local and global levels such as Teach for Madagascar, self-designed - undergraduate, Berkeley Science Network, graduate, and the California Alliance, graduate, National Organization for the Professional Advancement of Black Chemists and Chemical Engineers, NOBCCHe, post-doctoral and, faculty member. These efforts have had a broader impact on underrepresented groups participating in the sciences.
