SYNTHESIS AND ELECTRON-TRANSFER PROPERTY OF PHTHALOCYANINE DERIVATIVES

Metal phthalocyanine derivatives exhibit high redox abilities. In this paper, soluble metal phthalocyanine derivatives, cobalt phthalocyanin e tetrasulfonic acid and cobalt phthalocyanine octacarboxylic acid hav e been synthesized. Cyclic voltammograms and other electrochemical mea surements were carried out for their cobalt phthalocyanine derivatives in order to estimate their electron transfer abilities and electroche mical mechanism in an organic solvent. Electrode processes were diffus ion controlled at almost one electron transfer involving some weak ads orption and having the following chemical reaction. (C) 1997 Elsevier Science S.A.
