Chemically Modified Carbon Electrodes. XVII. Metallation of Immobilized Tetra(Aminophenyl)Porphyrin with Manganese, Iron, Nickel, Copper and Zinc, and Electrochemistry of Diprotonated Tetraphenylporphyrin.
Abstract
Tetra(aminophenyl)porphyrin can be amide-bonded to oxidized glassy carbon surfaces following activation with acetyl chloride or thionyl chloride, with the latter affording higher coverage. The immbolized porphyrin can be metallated with manganese, iron, colbalt, nickel, copper and zinc. The metalloporphyrins undergo electrochemical reactions in DMSO solvent at metal and ring-centered reduction potentials expected on the basis of solution molecular analogs. In the case of iron-metallated porphyrin, electrochemistry can be done in aqueous acid, where a clear but porphyrin-debilitating dioxygen catalysis is observable. (Author)
