Abstract :In this study, 1-benzylpiperidin-4-oxy substituted non-peripheral and peripheral metal free (3, 7), chloro manganese (III) (4, 8), oxotitanium (IV) (5, 9) and Cu(II) (6, 10) phthalocyanine complexes are synthesized and electrochemical properties were examined. Novel phthalocyanines compounds have been characterized by Fourier transform infrared, electronic spectroscopy, and mass spectra. Electrochemistry of non-peripherally and peripherally tetra-[(1-benzylpiperidine-4-yl)oxy] substituted metal-free and metallophthalocyanines were investigated by cyclic voltammetry (CV). Owing to the redox inactivity of the metal-free and Cu2+ ion of H2Pcs (3, 7) and CuPcs (6, 10), Pc based reductions and oxidation processes are recorded. Unlike, electrochemical analyses showed that MnPcs (4, 8) and TiPcs (5, 9) illustrated metal based redox processes in addition to the Pc ring based reactions.
