Abstract: Porphyrins containing different substitute groups on the base of phenyl and different metalloporphyrins (Fe,Co,Ni,Cu,Zn) were studied by means of the cyclic voltammetry (CV) in the DMF solution withtetrabutyl ammonium perchlorate (TBAP) as supporting electrolyte. The results indicate that the stronger the electronic attractive effect of substitute group is, the easier the porphyrin ring is reduced. The different metallic ions make the redox potentials of porphyrin ring shift to more negative potential, of which the shift made by zincion is the biggest.
