英文摘要	分别测定四-(三氟乙烷氧基)酞菁锌(ZnPcF)于非水溶剂N,N-二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)及磷酸盐缓冲溶液(PBS)中玻碳(GC,抛光)电极的循环伏安行为.结果表明,ZnPcF在DMF及DMSO溶剂均呈现4对电流峰,半波电位分别为0.558、-0.761、-1.034和-1.417 V,显示该物存在4个准可逆酞菁配体的单电子转移过程.而在PBS溶液中,ZnPcF乳化液仅呈现两个电流峰,半波电位为-0.885和-1.104 V,为不可逆反应特征,与酞菁锌(ZnPc未取代)相比,由于其周边取代基—三氟乙烷氧基的吸电子作用,导致氧化还原电位正移.; The cyclic voltammetric performance of ZnPcF in N,N-dimethylformaide(DMF),dimethyl sulfoxide(DMSO) solution and phosphate buffer solutions(PBS) has been examined.The results showed that four pairs of redox peaks appeared in nonaqueous solvents,and the values of half-wave redox potential were 0.558 V,-0.761 V,-1.034 V,-1.417 V,respectively,exhibiting four quasi-reversible phthalocyanine ligand based one-electron transfers.In PBS only two redox peaks were observed and the values of half-wave redox potential were-0.885 V,-1.104 V,exhibiting irreversible behavior characteristics.Comparing to the zinc phthalocyanine(unsubstitute ZnPc),introducing electron-withdrawing groups-trifluoroethoxyl to the peripheral sites of the phthalocyanines shifts the redox processes of the complex toward positive potentials.; 作者联系地址：福建医科大学药学院;; Author's Address: College of Pharmaceutical,Fujian Medical University,Fuzhou 350004,China
