Abstract

Photoinduced processes of a newly synthesized subphthalocyanine- diazobenzene-fullerene triad have been studied by the time-resolved spectroscopic techniques. On photo-excitation of subphthalocyanine (SubPc) moiety, the fluorescence quenching of SubPc was observed, suggesting the energy-transfer process from singlet excited energy of the light-harvesting SubPc to C60 through diazobenzene. This finding is confirmed by the nano-second transient absorption of the triplet excited state of C60.
