The influence of solvent, supporting electrolyte and electrolysis modes on poly-5,10,15,20-tetrakis(p-aminophenyl)porphyrin film growth were studied by the quartz crystal microbalance method. Electropolymerization was carried out in potentiostatic and potentiodynamic modes from dichloromethane and ethanol solutions. Tetrabutylammonium perchlorate (TBAP) and tetrabutylammonium hexafluorophosphate (TBAHFP) were used as supporting electrolytes. Surface micrographs of films electrodeposited over a different number of cycles of potential variation were obtained. The specific surface area, the pore size, and the thickness of the obtained polyporphyrin films were determined. The number of electrons participating in 5,10,15,20-tetrakis(p-aminophenyl)porphyrin electropolymerization was determined by the quartz crystal microbalance method. Based on the electronic absorption spectroscopy results, it was established that porphyrin macroheterocycles were preserved in an oxidized state in polyporphyrin.
