Synthesis and electrochemical properties of phthalocyanine-fullerene hybrids

Phthalocyanines linked to C-60 have been synthesized by two general strateg ies. One of them involves the addition of an azomethine ylide prepared in s itu from a formyl phthalocyanine to C-60, and the other one involves a stat istical condensation of two substituted phthalonitriles. one of them bearin g the C-60 moiety covalently attached. These new phthalocyanine-fullerene d yads have been studied by cyclic voltammetry and Osteryoung square wave vol tammetry, and inter- and intramolecular electronic interactions between the two electroactive subunits have been demonstrated.
