Abstract

Abstract: The investigation of the electrooxidation processes of(OEP)Co(Ⅱ)was carried out utilizing cyclic voltammetry(CV),electrochemical CV titration and in-situ thin-layer UV-Visible spectroelectrochemistry in 1,2-dichloroethane solution.It was indicated that Br can coordinate axially with(OEP)Co(Ⅱ)and three one-electron oxidation steps lead(OEP) Co(Ⅱ)to the formation of five-or six-dentate coodination species.The formation constants of these species were estimated.The electrooxidation mechanism of(OEP)Co(Ⅱ)in the presence of Br~-anions was given.

Key words: bromide anion, eobaltous oetaethylporphyrin, electrooxidation, electrochemistry, spectroelectrochemistry
