Electrochemical and Photophysical Properties of a Novel Polythiophene with Pendant Fulleropyrrolidine Moieties: Toward Double Cable Polymers for Optoelectronic Devices

We have prepared a novel bithiophene carrying a fulleropyrrolidine substituent. Its electrochemical polymerization affords an electron donor- acceptor material that has been studied by means of electrochemical and spectroscopic techniques. The results from photoinduced absorption and light-induced electron spin resonance experiments demonstrate a photoinduced electron transfer from the polythiophene backbone to the tethered acceptor moieties.
