Abstract

The
novel dinitrile compound (3) and peripherally tetra
2-(4-benzyloxyphenyl)ethanol substituted metal-free (4), zinc(II) (5),
cobalt(II) (6) and copper(II) (7) phthalocyanines were synthesized and
characterizated for the first time in this study. Electrochemical
characterization of metal-free and metallophthallocyanines were determined by
using cyclic voltammetry (CV) and square wave voltammetry (SWV) techniques. Metal-free and metallophthalocyanines having
redox inactive centers (Zn⁺², Cu⁺²) showed similar Pc
based electron transfer processes. On the other hand, Co^II metal ion
behaves as redox active cations in the core of the Co- phthalocyanine.
Therefore, Co- phthalocyanine gives one metal based reduction reaction
[Co^IIPc^-2] / [Co^IPc^-2]^-1.
