ABSTRACT
An elementary electron transfer reaction A + D = A−• + D+• in principle can be sensitized by both a homogeneous and a heterogeneous photosensitizer. Typical examples for the former are organic compounds or metal complexes having charge-transfer (CT) character. eir basic action can be described
