Electroanalytical characterization of chloroquinoline substituted redox-active phthalocyanines

Abstract

In the first part of this study, the synthesis and characterization of organosoluble 5-chloroquinolin-8-yloxy substituted iron(II) (2) and oxo-titanium (IV) phthalocyanines (3) are reported for the first time. These compounds have been characterized by elemental analysis, Fourier transform infrared, electronic spectroscopy, and mass spectra. Electrochemical behaviors of metal-free and cobalt phthalocyanines and further new types of iron and oxo-titanium phthalocyanines were investigated using electroanalytical methods, such as cyclic (CV) and square wave voltammetry (SWV). According to the electrochemical results, phthalocyanines by and large showed one-electron metal- and/or ligand-based reversible or quasi-reversible reduction and oxidation processes. All in all, this study's results inevitably create a useful way to use them in possible future studies, which will particularly attempt to use the compound investigated in potential areas of use.
