Photoinduced energy and electron transfer between oligothienylenevinylenes and N-methylfulleropyrrolidine (MP-C60) has been studied in details. MP-C60acts as an electron acceptor.N-Methylfulleropyrrolidine is an acceptor molecule with a fullerene core, and a nitrogen free lone pair that is located at the pyrrolidine ring. It can be used as an intermediate in the synthesis of other functionalized fullerenes. It can be also used in the development of opto-electronic devices.Soluble functionalized fullerene. Acts as electron acceptor in mixtures or when linked to π-conjugated molecules and polymers. Used as spectroscopic and redox reference for C60-based molecular heterojunctions.
