Photoinduced charge and energy transfer involving fullerene derivatives

Abstract

In this feature article, a brief overview over the photoinduced energy and charge transfer mechanisms involving fullerenes will be presented. The photoinduced charge separation between organic donor and acceptor molecules is the basic photophysical mechanism for natural photosynthesis and nearly all organic solar cell concepts. We will give a short introduction to the mechanisms of excited state charge transfer and resonant energy transfer and present examples of relevant applications in organic optoelectronics and photodynamic tumor therapy.
