TY - JOUR ID - 31852 TI - ELECTROCHEMICAL INVESTIGATION OF OCTAETHYL PORPHYRIN IRON(III) CHLORIDE IN THE PRESENCE OF PYRIDINE, IMIDAZOLE AND COLLIDINE: AN APPROACH TO THE ROLE OF PYRIDINE IN THE COUPLED OXIDATION JO - Journal of Sciences, Islamic Republic of Iran JA - JSCIENCES LA - en SN - 1016-1104 Y1 - 2000 PY - 2000 VL - 11 IS - 2 SP - EP - DO - N2 - Cyclic voltammogram and differential pulse polarograph of octaethyl porphyrin iron(III) chloride in dichloromethane was investigated in the presence of pyridine, imidazole and collidine. Values of E1/2 for FeIII/FeII redox reaction were monitored as a function of axial group concentration, and on the basis of these data, an overall oxidation-reduction and ligand addition scheme was formulated. Addition of pyridine resulted in anodic shift for oxidation wave from –0.16 V to –0.06 V while for imidazole and collidine we observed a cathodic shift.
