Electrochemical synthesis of cobalt polyporphine films

A method for modification of the inert electrode surface with an electroactive polymeric film containing the CoN4 catalytic site has been suggested and approved. The described approach affords the maximal content of the metal porphine moiety per unit weight of the coating. The classical method of introduction of an ion into the porphine macrocycle has been replaced by electrochemical polarization of an electrode with a metallated film in a dilute solution. The metalation efficiency has been demonstrated by the presence of changes in the current-voltage and spectral characteristics of the resulting polymeric films of the unsubstituted porphine pH(2)P and cobalt polyporphine pCoP.
