The synthesis of new metal-free, nickel, zinc, cobalt and copper phthalocyanines with four 6-oxyquinoline groups on the non-peripheral position were prepared by cyclotetramerization of a novel 3-(quinolin-6-yloxy)phthalonitrile. All new compounds were characterized by the ways of IR, 1H NMR, 13C NMR and MS spectral data, all of which were compatible with the proposed structures. Electrochemical properties of metal-free, Ni(II) and Zn(II) phthalocyanines were investigated by using cyclic voltammetry and differential pulse voltammetry techniques. The metal-free phthalocyanine exhibits two reversible Pc ring-based one-electron reduction couples. The Ni(II) and Zn(II) phthalocyanines give very similar voltammetric responses with slightly potential shift due to the different metal center.
