Role of Porphyrins and Chlorophylls in Artificial Photosynthesis

摘要

The primary objective for studying artificial photosynthesis is to understand how to induce electron transfer out of an excited singlet state of a donor to a nearby acceptor on a time scale faster than other processes. It is equally important to understand how to stabilize the resulting charge-separated state with respect to the ground state. The model systems use porphyrins and chlorophylls as sensitizers of light-induced electron transfer. Both foward and reverse reactions are being studied systematically with the goal of optimizing the efficiency of charge separation and the kinetics of charge stabilization. Accomplishments in this field are reviewed. (ERA citation 08:012816)
