Department Seminar: Professor Leslie J. Murray
Professor Murray earned his Bachelor of Arts degrees in chemistry and biology from Swarthmore College, and earned his doctorate in inorganic chemistry at the Massachusetts Institute of Technology, focusing on component interactions and dioxygen activation in the toluene/o-xylene monooxygenase system. He then was a post-doctoral researcher at the University of California, Berkeley, working on gas storage and separation using metal–organic frameworks. He joined the faculty at the Unversity of Florida in 2010, and is affiliated with the National High Magnetic Field Laboratory.
Professor Murray's research focus is to design, synthesize, and evaluate transition metal complexes for small molecule activation. In particular, his group is interested in energy-related processes, such as water oxidation, carbon dioxide reduction, and dioxygen reduction. Metal clusters housed within the active sites of proteins carry out basic and challenging redox reactions, such as carbon dioxide reduction or nitrogen fixation. Researchers expect that well-defined and tunable metal clusters can function as highly efficient catalysts in synthetic systems. The goal is to develop multimetallic complexes in which a tunable ligands controls the assembly and environment of each metal ion within a cluster (e.g., donor atom type, metal-metal distance). Importantly, one design criterion is that complexes retain an active site, which we anticipate will afford selective reactivity with substrates and increase the catalytic efficiency.
