Synthesis and Photophysical Properties of Electron-Rich Perylenediimide-Fullerene Dyad

Abstract

An electron-rich perylenediimide-C60 dyad has been prepared to explore a new type of donor−acceptor system. Time-resolved absorption measurements in benzonitrile revealed unambiguous evidence for the formation of a charge-separated state consisting of perylene diimide radical cation and C60 radical anion via photoinduced electron transfer, showing a new class of artificial photosynthetic models in terms of charge separation
