Description
Summary:The phthalonitrile (3) and triazole substituted metallo phthalocyanines (MPc) (4–7) were prepared. The novel compounds were characterized with spectroscopic data. Electrochemical analyses of metallophthalocyanines (4–7) bearing triazole substituents were performed to investigate redox activity of phthalocyanines (Pcs) ring. While incorporation of Ni2+ and Cu2+ cations in the Pc core only influenced peak positions of Pc ring processes, Co2+ and Cl1−Fe3+ cations of CoPc and FePc gave extra redox couples to the Pc based ones. Releasing the axial Cl1− anion on Fe3+ cation of FePc during the reduction reactions complicated the redox responses. Redox reactions of Co2+ and Fe3+ metal centers also considerable influenced spectral and color responses of these complexes.
