Abstract

Fullerene derivatives in which an oligophenylenevinylene (OPV) group is attached to C60 through a pyrrolidine ring have been prepared by 1, 3-dipolar cycloaddition of the azomethine ylides generated in situ from the corresponding aldehydes and sarcosine. Electrochemical and photophysical studies have revealed that ground-state electronic interactions between the covalently bonded OPV moiety and the fullerene sphere are ...
