Abstract

In this study, peripheral and non-peripheral tetra dimethyl 5-oxyisophthalate substituted cobalt(II), manganese(III) and mu-oxo-dimer Fe(III) phthalocyanines Were synthesized by the reaction of dimethyl 5-hydroxyisophthalate with 1,2-dicyano-4-nitrobenzene/1,2-dicyano-3-nitrobenzen in dry N,N-dimethylformamide in the presence of anhydrous potassium carbonate. All purified phthalocyanine compounds were characterized by using FT-IR, UV-visible, MALDI-TOF mass spectrometry and elemental analyses results. Electron transfer properties of all novel cobalt(II), manganese(III) and mu-oxo-dimer Fe(III)phthalocyanine complexes were investigated by voltammetric and in situ spectroelectrochemical measurements in nonaqueous solution medium. Complexes were observed to display both metal-based and phthalocyanine ring-based reduction and oxidation electron transfer processes. (C) 2015 Elsevier Ltd. All rights reserved.
