Spectroscopic and Electrochemical Studies of the Transition Metal Tetrasulfonated Phthalocyanines. Part 5. Voltammetric Studies of Adsorbed Tetrasulfonated Phthalocyanines (MTsPc) in Aqueous Solutions.

Abstract

Cyclic voltammetric measurements of adsorbed Fe- and Co-tetrasulfonated phthalocyanine (TsPc) and Co-phthalocyanine (Pc) have been carried out on ordinary pyrolytic graphite and silver electrodes at different solution pH ranging from 1 to 13. Many voltammetry peaks were found to be pH dependent with a slope of -59 mV/unit pH. In some instances this dependence was observed in alkaline or acid solutions only. Explanations for the various voltammetry peaks and their pH dependence are discussed. The influence of dioxygen and its reduction have also been examined. Keywords: Macrocycles, Tetrasulfonated phalocyanines, Adsorption layers, Electrochemical properties, Voltammetry.
