Abstract
The ability to oxidatively polymerization from a solution in ethanol of tetraphenylporphyrin derivatives: 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin, 5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin, Zn-5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin, Zn-5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin were studied. The polymerization of 5,10,15,20-tetrakis(3-hydroxyphenyl)porphyrin does not occur; three of the four studied porphyrins form thin transparent polyporphyrin films tightly adhered to the electrodes surface. The influence of the nature of the monomer, the deposition mode, and the supporting electrolyte used on the process of electropolymerization and the properties of the deposited polyporphyrin films were studied. The spectral changes observed during the deposition of the films indicate that the generation of the polyporphyrin films occurs through the formation of C–O–C bonds and the keep of the porphyrin macroheterocycle in polyporphyrin.
