Popis:	New thin ffilms of meso -tetrakis[2,2]- para -cyclophanyl metalloporphyrin ccomplexes with Mn(II), Fe(II), Co(II) and Ni(II) were studied using electrochemical methods and UV-Vis thin-layer spectroehemistry. These polymeric films are if interest both for their significant electrical conductivity and as electrode coating materials that exhibit new patterns of catalytic reactivity in the reduction of oxygen. All of the films show a catalytic effect in the reduction of oxygen in acidic as well an basic media. Electroreduction of oxygen on the new polymeric porphyrins promotes the four-electron reduction directly to water.
