| Abstract: | Water soluble bisviologen linked zinc porphyrin (ZnP(C4VAC4VB)4) was synthesized and characterized. The quenching processes of the photoexcited singlet state and triplet state of ZnP(C4VAC4VB)4 were measured by using fluorescence lifetime and laser flash photolysis. The photoexcited singlet state of the zinc porphyrin was quenched by the bonded bisviologen. Photoinduced hydrogen evolution with ZnP(C4VAC4VB)4 and hydrogenase was observed under steady state irradiation. |
