| Abstract: | The Oxidation-reduction Characterization of tetrabenzoporphyrin vanadium oxide (VO-TPP), p-tetrachloroporphyrin vanadium oxide (VO-TC1PP) and tetrapyridylporphyrin (VO-TPyPP) were investigated by cyclic voltammetry in dimethylsuoxide(DMSO). The results prove that the oxidation-reduction processes of above porphyrins are quasi-reversible. The half wave potential of VO-TC1PP]/VO-TC1PP]4- is -0.781 V and that of VO-TC1PP]4-/VO-TC1PP]5- is - 1. 141 V. The repulsive electron radical groups are beneficial to the stability of central ions of porphyrin comlexes. |
