摘要：

Tetrasulfonated copper and cobalt phthalocyanines have been bound to SnO2 electrode surfaces modified by either (γ-aminopropyl)triethoxysilane or 3-(N-(2-aminoethyl)aminopropyl)trimethoxysilanes. The electrochemical behavior of the surface bound dye was compared with that of the solution and absorbed forms at SnO2 in Me2SO and aqueous media. A stable reversible redox couple was seen on the cobalt phthalocyanine electrodes/SnO2 in aqueous media. Concentrations of surface bound phthalocyanines were easily detected by monitoring the Cu(2p1/2,3/2) and N(1s) X-ray photoelectron transitions. SnO2 electrodes with bound phthalocyanine and SnO2 electrodes in contact with solutions of phthalocyanines showed similar photoelectrochemical response to the oxidation of oxalate or ascorbate. © 1979 American Chemical Society.
