Synthesis, spectral and electrochemical characterization of mercaptopyrimidine-substituted cobalt, manganese and Zn (II) phthalocyanine complexes

A new family of thiol-derivatized metallophthalocyanine has been synthesized. The electrochemical behaviors of the complexes have been investigated. The modified glassy carbon electrode using the electropolymerized manganese complex (poly-MnTMPyrPc) was characterized in aqueous solution. The result...
