2-aminoethylthiol Substituted Cobalt and Manganese Phthalocyanines: Spectroscopic and Electrochemical Investigations

Abstract

Spectroscopic and electrochemical properties of 4-(2-aminoethylthio phthalocyanato complexes of cobalt (complex 3) and manganese (complex 4) are investigated in this work. The UV-Vis spectral properties of the complexes were typical of the nature of central metal (cobalt versus manganese) phthalocyanine. The Q-band of manganese 4-(2-aminoethylthio) phthalocyanine is red shifted with respect to cobalt manganese 4-(2-aminoethylthio) phthalocyanine. Solution electrochemistry of complex 3 showed three distinctly resolved redox.....
