摘　　要：利用循环伏安法研究了两种中位具有不同取代基的卟啉和它们过渡金属配合物在DMF溶液中以四丁基高氯酸胺(TBAP)为电介质的电化学性质,取代基的吸电子能力越强,卟啉越容易被还原.不同金属离子均使卟啉的氧化还原反应向负值移动,其中Zn负移最大.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 zinc ion is the biggest.
