[60]Fullerene and TCNQ donor–acceptor crystals of octakis(dimethylamino) porphyrazine

Abstract

Reaction of octakis(dimethylamino) porphyrazine 1 with [60]fullerene gives a crystalline 2:1 charge-transfer (CT) complex as a three-dimensional network of chains; in contrast, reaction of 1 with tetracyanoquinodimethane (TCNQ) gives a crystalline 1:1 charge transfer salt as one-dimensional integrated stacks.
