A Sequential Photoinduced Electron Relay Accelerated by Fullerene in a Porphyrin‐Pyromellitimide‐C₆₀ Triad

Abstract

A model for the reaction center of photosynthesis is the porphyrin-imide-C60 triad 1. The C60 unit accelerates quenching of the excited singlet state of the porphyrin group. Thus, electron transfer can proceed either by a two-step process through the imide spacer with formation of a long-lived intermediate with seperated charge or directly through space.
