Professional Interests
Inorganic, catalytic, oxidation-reduction chemistry. The development of highly selective and efficient catalysts for the oxidation of inorganic and organic substrates under mild conditions is the ultimate objective of catalytic chemists. An oxidation mechanism could be as simple as an outer sphere electron transfer event, such as a self-exchange reaction, or as complicated as a scheme involving several bond making and bond breaking events, such as the enzyme catalyzed production of carbohydrates from CO2, H2O and light in chlorophyll containing plants. Through elucidation of mechanisms by which these transformations are effected, the researcher is able to fine-tune structural design to mimic the natural systems or to increase oxidant efficiency, i.e. to increase the number of turnovers, to increase selectivity toward the desired product, or to utilize milder reaction conditions. We explore the kinetic nuances and mechanistic implications of electron transfer reactions in which there are changes in proton content. Proton coupled electron transfer (PCET) is an important process for biological systems and energy conversion, including photosynthesis and respiration. Our studies focus on the synthesis and reactivity of catalysts that mimic the active sites of naturally occurring electron transfer systems. In particular, our lab is conducting investigations into the design of molecular units that mimic the function of the oxygen evolving complex of photosystem II (PSII). Our group is particularly interested in how tuning the redox properties of the catalyst leads to selectivity in oxidation.
