摘要：

The method of cyclic voltammetry was used to study electrochemical properties of derivatives of tetraphenylporphyrin in dichloromethane. In the case of substituted tetraphenylporphyrin, as dependent on the nature of substituents at the periphery of the porphyrin ring, reduction of porphyrins occurs in the range of negative potentials resulting in formation of a pi-anion-radical and dianion, while oxidation of porphyrins with formation of a pi-cation-radical and dication occurs in the range of positive potentials. In the case of tetrakis(p-aminophenyl)porphyrin, a poly-porphyrin film is formed on the electrode in the course of electrooxidation. The method of chronoamperometry was used to determine the potential of initiation of electropolymerization of H2T(p-NH2Ph)P.
