N2 - Photoinduced electron transfer (PET) and enhancement of fluorescence were observed simultaneously for a series of donor-acceptor-type C 60 pearl-necklace polymers, contradicting the conventional notion that the formation of charge-separated state derived from electron transfer (ET) causes the quenching of fluorescence. The quantum yield o f of the present polymers was one to two orders of magnitude larger than that of the pristine C 60 . On the other hand, light-induced electron spin resonance (LESR) signals, exhibiting signatures of both the aromatic diamine component cation and the C 60 anion, implied the formation of an ion-radical pair caused by the PET.
