The synthesis and characterization of novel peripherally-tetra substituted metal-free 4 and metallophthalocyanines 5-7 are described for the first time in this study. All the new compounds are characterized by a combination of IR, 1H and 13C NMR, mass and UV-vis spectroscopy techniques. Electrochemical and spectroelectrochemical properties of metal-free, nickel(II), cobalt(II) and copper(II) phthalocyanines were investigated by using cyclic voltammetry and square wave voltammetry techniques. While all complexes give common reduction processes, they electropolymerized on the working electrode. Applied potentials and type of the metal center of the complexes affect the electropolymerization mechanism. Spectroelectrochemical and electrocolorimetric measurements exhibit that electrogenerated anionic species of the complexes have distinct color differences which are desire factors for electrochromic application of the complexes.

The synthesis and characterization of novel peripherally tetra-substituted iron(II) 4 and cobalt(II) 5 phthalocyanines are described for the first time in this study. All the new compounds are characterized by a combination of IR, 1H and 13C NMR, mass and UV-vis spectroscopy techniques. Complexes 4 and 5 served as catalyst for the oxidation of cyclohexene using different types of oxidants, such as tert-butyl hydroperoxide (TBHP), m-chloroperoxybenzoic acid (m-CPBA), aerobic oxygen and hydrogen peroxide (H2O2). During the oxidation process the products formed are 2-cyclohexene-1-ol, 2-cyclohexene-1-one and cyclohexene oxide. The selectivity for 2-cyclohexene-1-ol is favored when iron(II) and cobalt(II) phthalocyanine catalysts are employed. The higher conversion is obtained as catalyst iron(II) phthalocyanine (96%). TBHP was determined as the successful oxidant with the minimum demolition of the catalyst, superior selectivity and conversion in the oxidation products.
