Substituted phthalocyanines and their electropolymerization properties

• Synthesis of substituted phthalonitrile.
• Preparation of phthalocyanine complexes.
• Investigation of the electrochemical properties of H2-Pc, TiIVOPc, CoIIPc.

In this study, new metal-free and metallo-phthalocyanine complexes (Co, TiO) were synthesized using a piperazine-substituted phthalonitrile derivative. All proposed structures were supported by instrumental methods. Electrochemical studies of H2-Pc, TiIVOPc, and CoIIPc were examined using cyclic voltammetry (CV) and square-wave voltammetry (SWV) techniques. Voltammetric analyses of phthalocyanines supported the proposed structure of the synthesized complexes. All studied phthalocyanines were oxidatively electropolymerized on the working electrode during the repetitive anodic potential scans.
