Syntheses, Characterization and Modification of Transition Metal Octacarboxyphenoxy Phthalocyanines Complex on Gold Electrode

The materials used in this work were the first-row transition metals octacarboxyphenoxy phthalocyanines complexes. The complexes were synthesized and immobilized onto gold electrode surfaces. The immobilization method used to modify gold electrode was highly stable. The complexes improved the efficiency of the gold electrodes . Modification of electrodes with MPcs protects the electrode surfaces from chemical fouling, provides enhanced catalytic properties, improves sensitivity and selectivity. The complexex and the electrode surfaces were characterized using Fourier transforms infrared (FT-IR) spectroscopy, Ultra-violet Spectroscopy, Mass spectroscopy (MS), Magnetic circular dichroism (MCD), Nuclear magnetic resonance spectroscopy (NMR), Ultraviolet/visible absorption spectroscopy (UV- Vis) , Elemental Analysis
