The films formation via activated by oxygen electrochemical oxidation of hydroxy-phenylporphyrin and its zinc complex in dimethyl sulfoxide media was demonstrated. The different kinetics of deposition and morphologies of the films were observed. During the film deposition the working electrode surface was passivated in case of porphyrin-ligand, and was not passivated in case of metal complex. As a result, the electrochemical method leads to suf-ficiently thick films with a globular structure based on the metal complex and films o small thickness films and layered structure based on the porphyrin-ligand.

Key words: 2H-5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin, Zn-5,10,15,20-tetrakis(4-hydroxy-phenyl)porphyrin, electropolymerization, morphology, kinetics
