Visible light-harvesting perylenebisimide-fullerene (C60) dyads with bidirectional "ping-pong" energy transfer as triplet photosensitizers for photooxidation of 1,5-dihydroxynaphthalene.

Visible light-harvesting perylenebisimide (PBI)-C(60) dyads were prepared as organic triplet photosensitizers for photooxidation of 1,5-dihydroxynaphthalene and the efficiency of the dyads is 6-fold of the conventional Ir(III) complex triplet photosensitizer.
