These efforts resulted in several significant milestones including the experimental realization of “metalloaromaticity” (the concept that metallic rings may also display traditional aromatic behavior as exhibited by benzene)\, synthesis of the first molecule containing a boron-boron double bond—the first “diborene”\, and synthesis of the first molecule containing a triple bond between two main group metals (the gallium analog of acetylene). Research efforts have also concerned carbene stabilization of highly reactive main group molecules such diphosphorus (P2)\, diarsenic (As2)\, and disilicon (Si2). This presentation will prominently feature our efforts to synthetically augment the molecular template of N-heterocyclic carbenes and their surprising conversion to stable dithiolene-based chemical radicals\, which have shown promise in the activation of small molecules\, such as ammonia. \n\n\n\nLearn more about Professor Robinson: https://www.gregoryhrobinson.com/ \n\n\n\nSelected Awards: \n\n\n\n\nAmerican Academy of Arts and Sciences (elected in 2025)\n\n\n\nNational Academy of Sciences (elected 2021)\n\n\n\nFellow of the Royal Society of Chemistry (2017)\n\n\n\nF.

Williams Hall of Life Sciences\, Room 060 \n\n\n\nPublic Lecture: \n\n\n\n\n\n\n\nFrom Hydrogen to Radon: Playing the ‘Long Game’ in Inorganic Chemistry \n\n\n\nFrom the syntheses of the first molecules containing boron-boron double bonds—the first “diborenes”—to the first molecule shown to possess a triple bond between two main group metals—the first “gallyne”—a digallium analog of acetylene\, the Robinson Laboratory has made noteworthy contributions to Inorganic Chemistry. Consequently\, in addressing foundational issues of structure and bonding\, fascinating new areas of chemistry have emerged from the Robinson laboratory such as metalloaromaticity (the realization that properly constrained metallic ring systems can display traditional aromatic properties\, thereby mimicking the chemical behavior of benzene)\, multiple-bonding involving heavier main group elements\, stabilization of silicon dioxide-based precursors to “molecular sand”\, dithiolene-based aluminum tri-radicals. These discoveries will be summarized and placed in historical context.

S. Martin\, PhD\, Associate Professor\, Chemistry; Biochemistry & Molecular Biology\, The College of Wooster\n\n\n\n“Molecular Makeovers: From Simple Precursors to Bio‑Relevant Heterocycles”\n\n\n\n\n\n\n\nQuinolinones and coumarins are related nitrogen- and oxygen-containing heterocycles that appear in a variety of bioactive molecules\, including pH probes\, natural products\, and pharmaceuticals. Despite their importance\, certain isomers of these molecules are hard to make. Most current synthetic routes to access 7-substituted quinolinones and coumarins either work for only a narrow set of starting materials or require multiple steps that change oxidation states after the molecule’s carbon framework is already built. These approaches limit how easily chemists can explore new structures. \n\n\n\nResearch in the Martin lab has taken a different strategy to build quinolinones\, forming the carbon skeleton from simpler building blocks using a two-step reaction sequence that converts meta‑substituted anilines and methyl 3\,3‑dimethoxypropionate to mainly 7‑substituted quinolinones. This seminar will discuss recently published studies aimed at understanding what controls the ratio of the two isomeric products and more recent work aimed at 1) developing milder reaction conditions for this transformation  2) synthesizing interesting biologically relevant quinonliones\, and 3) optimizing reaction conditions for coumarin synthesis. \n\n\n\n\n\nLocation: Ruth W.

Williams Hall of Life Sciences\, Room 060 \n\n\n\nLunch RSVP: Sign up \n\n\n\nAbstract:\n\n\n\nUnderstanding protein–protein interactions (PPIs) is central to deciphering cellular processes\, as proteins are the primary functional molecules within cells. Peptides and aptamers\, which occupy a strategic niche between antibodies and small molecules\, have emerged as powerful tools for probing and modulating PPIs. \n\n\n\nPeptides serve as highly versatile ligands\, recognizing proteins through hydrogen bonding\, van der Waals forces\, and ionic interactions. They can be chemically synthesized at low cost\, possess low molecular weight\, and exhibit enhanced tissue and cellular penetration\, making them highly attractive for both research and therapeutic applications. Aptamers\, short single-stranded RNA or DNA molecules\, fold into unique three-dimensional structures that enable tight\, highly specific binding to diverse molecular targets. As compelling alternatives to antibodies\, aptamers—especially DNA-based ones—offer long shelf life\, low toxicity\, minimal immunogenicity\, cost-effective chemical synthesis\, and broad tolerance for chemical modifications\, positioning them as versatile candidates for diagnostics\, targeted therapy\, and drug development. \n\n\n\nIn this talk\, I will present our recently developed aptamers and peptides targeting the PD-1/PD-L1(2) axis. These novel ligands provide a next-generation strategy for modulating PPIs\, opening new avenues for therapeutic intervention and translational applications in immuno-oncology. \n\n\n\nBio:\n\n\n\nDr. Xiaohong Tan earned his Ph.D. from Nanyang Technological University\, Singapore. After completing postdoctoral training at the Center for Nucleic Acids Science and Technology at Carnegie Mellon University\, USA\, he began his independent research career in the Department of Chemistry at Bowling Green State University\, USA\, where he was promoted to Associate Professor with tenure in 2025. His research expertise encompasses nucleic acid chemistry\, peptide chemistry\, and protein biochemistry\, with a particular focus on developing aptamer- and peptide-based probes for precise protein recognition to investigate protein–protein and protein–nucleic acid interactions.

Williams Hall of Life Sciences\, Room 045. \n\n\n\nOrganic chemistry has a role to play in meeting the global demand for energy. Porphyrin-based electron donors\, which harvest light exceptionally well\, have potential as the next generation of materials in solar energy conversion. Individual pieces can self-assemble into a stacked “molecular ladder” through hydrogen bonding and other noncovalent interactions. The design is beautiful\, but the execution is… sometimes hard. Multi-step synthetic organic chemistry sometimes turns perfectly good ideas into challenges with solubility\, reactivity\, and fundamental design. These obstacles are common in research\, so progress depends not so much on the absence of failure but the ability to evaluate experiments quickly and to learn from every step along the way.

Williams Hall of Life Sciences\, Room 060 \n\n\n\nAbstract:\n\n\n\n\n\n\n\nHow do microbes live on the pollutant carbon monoxide? How do microbes split the triple bond of nitrogen gas? When it comes to performing difficult chemistry\, microbes often combine a protein scaffold with a highly reactive metallocofactor; they essentially employ a “hired gun.” The Drennan lab combines X-ray crystallography and cryo-electron microscopy with other biophysical methods to reveal the secrets behind metalloenzyme chemistry. In this seminar\, Drennan will present her lab’s structural studies of ribonucleotide reductases (RNRs). RNRs use metallocofactors to generate radical species\, enabling the conversion of ribonucleotides (the building blocks of RNA) to deoxyribonucleotides (the building blocks of DNA). These enzymes are chemotherapeutic targets and proposed antibacterial targets. Here\, Drennan will describe how her lab has used biophysical methods to reveal RNR’s secrets.

Williams Hall of Life Sciences\, Room 060 \n\n\n\nThis talk is designed for and open to the general public. \n\n\n\nAbstract:\n\n\n\n\n\n\n\nProfessor Cathy Drennan of the Massachusetts Institute of Technology is fascinated by the molecular world. She wants to understand how protein molecules carry out the requisite work for cell survival. How do proteins transport cargo within a living cell? How do proteins break bonds into order to turn the building blocks of RNA into the building blocks of DNA? And importantly\, how can one watch a process that is too small to see? Research groups\, like the one that Drennan runs\, use biophysical methods to determine the three-dimensional structures of proteins at the atomic level. In this presentation\, Drennan will provide an overview of the methods that allow her to “see” the atoms that make-up protein molecules. She will tell you how she became an explorer of the molecular world. Her journey was not straightforward. In first grade\, she was diagnosed with dyslexia when she was not able to learn to read. By her second time through sixth grade\, she learned how to read by memorizing the shapes of words. Now she uses her shape-recognition abilities in her research to investigate the shapes of molecules. Drennan will share her journey and her research in a presentation designed for a general audience.
