摘    要:用循环伏安法研究了VO-TPP,VO-TClPP和VO-TpyPP的氧化还原特性。结果表明:这3种钒氧卟啉化合物的氧化还原过程存在准可逆性,VO-TClPP中钒氧中心离子的还原半波电位为—0.781 V,卟啉环的还原电位为—1.141 V。结果还表明:推电子基团有利于中心离子的稳定。

关 键 词:循环伏安  钒氧卟啉  氧化还原  半波电位

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.
Keywords:cyclic voltammetry  porphyrin vanadium oxide  oxidation-reduction  half-wave potential
