A fulleropyrrolidine with two oligophenylenevinylene substituents: synthesis, electrochemistry and photophysical properties

A fullerene derivative in which two oligophenylenevinylene ( OPV) groupsare attached to C-60 through a pyrrolidine ring has been prepared and photophysical studies in CH2Cl2 solution show that photoinduced energy transfer from the OPV moieties to C-60 occurs, and not electron transfer. On passing to a more polar solvent such as benzonitrile, again no evidence of electron transfer is found.
