Synthesis and Electrochemical Properties of Fullerenylstyrenes.

An efficient preparative method was developed for the synthesis of previously unreported fullerenylstyrenes based on the reaction of C60 fullerene with terminal acetylenes and EtMgBr in the presence of Ti(Oi-Pr)4. The voltammetric curves of the prepared fullerenylstyrenes were studied, and good prospects for their application as acceptor materials for bulk heterojunction solar cell were demonstrated.
