Photoinduced Intramolecular Electron Transfer in an Oblique Zinc Phthalocyanine-Viologen Linked System

Institute of Photographic Chemistry Academia Sinica Beijing 100101

Received Date: 22 April 1996

The spectroscopic properties and photoinduced electron transfer process have been studied in zinc phthalocyanine-viologen system with bisphenol A (ZnPcAV²⁺).It was found that the excited singlet state of zinc phthalocyanine moiety is quenched and the fluorescence lifetime is reduced by the linked viologen.Nanosecond laser photolysis studies showed that intramolecular quenching of the excited triplet state of zinc phthalocyanine moiety by the attached viologen occurred giving reduced viologen radical ion (V⁺) that survived over 50μs.
