Özet

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, H-1 NMR C-13 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 (C) 2010 Elsevier Ltd All rights reserved
