Synthesis and Photophysical Studies of a New Nonaggregated C_(60)-Silicon Phthalocyanine-C_(60) Triad

摘要

A C_(60)-SiPc-C_(60) triad showing no aggregation is synthesized and characterized. Photoexcitation of the triad results in formation of the charge-separated state by photoinduced electron transfer from the singlet excited state of the SiPc moiety to the C_(60) moiety. The charge-separated state has a lifetime of 5 ns in benzonitrile at 298 K.
