In contrast to proton-coupled electron transfer (PCET) reactions between molecules in their ground states, comparatively little is known about PCET reactions with electronically excited molecules. In order to reveal the pathways by which light absorption and proton/electron transfer can be integrated, we are examining excited-state PCET reactions in a series of model systems. Using transient absorption spectroscopy, we have obtained key mechanistic and kinetic information about this class of light-driven reactions.
