Electrochemical and spectroscopic characterization of a gold electrode modified with 3,4′,4″,4‴ copper(II) tetrasulphonated phthalocyanine

This paper describes an electrochemical and spectroscopic study of a gold electrode modified with 3,4′,4″,4‴ copper(II) tetrasulphophthalocyanine tetrasodium salt (CuTSPc). Its electrochemical behaviour is compared to that with random CuTSPc and cobalt(II) tetrasulphophthalocyanine tetrasodium salt (CoTSPc). In addition electrochemical and synchrotron radiation X-ray fluorescence measurements were performed to characterize the adsorbed copper surface concentration.
