We applied an original approach to the formation of polymeric porphyrin films based on chemical interaction between porphyrin and superoxide. In the present work, we showed the modification of surfaces of different working electrodes in the presence of one electroactive group (-OH or -NH2) in the porphyrin structure. We showed an essential role of desorption phenomena in the processes of film formation and found that the film desorption for aminophenyl porphyrins occurs at positive potentials, whereas the film desorption for hydroxyphenyl porphyrins occurs at negative onеs. In the future, these data will allow us to optimize the processes of film formation of both individual porphyrins and composites. In addition, we demonstrated a correlation between the parameter characterizing the rate of interaction between porphyrin and superoxide and the efficiency of film formation by the developed method, which creates prerequisites for quick screening of probable porphyrin structures for film formation.
