Abstract

The intermolecular electron transfer between carboxylic dendritic zinc(II) phthalocyanine bearing carboxylic terminal groups(G₁-ZnPc(COOH)₈) and methyl viologens (MV²⁺) was studied by steady-state fluorescence and UV/Vis spectroscopy. The effect of different concentrations of MV²⁺ on intermolecular electron transfer was investigated. The results show that the fluorescence emission of this dendritic phthalocyanine could be greatly quenched with an increasing amount of MV²⁺ upon excitation at 610 nm. Our study suggests that this novel dendritic phthalocyanine is an effective new electron donor and transmission complex and could be used as a potential biosensor conjugated with suitable fluorescence quencher.
