用微电极和薄层循环伏安（ＣＶ）技术研究了Ｂｒ－对四苯基钴卟啉（（ＴＰＰ）Ｃｏ）在１，２＿二氯乙烷（ＤＣＥ）中电化学行为的影响．发现在较高电位下，两个Ｂｒ－轴向配位的（ＴＰＰ）Ｃｏ（ＩＩ）（Ｂｒ－）２其一个Ｂｒ－发生脱落表现出（ＴＰＰ）Ｃｏ（ＩＩ）（Ｂｒ－）的行为特征，这被证明是Ｂｒ－的氧化所致．证明了（ＴＰＰ）Ｃｏ（ＩＩ）（Ｂｒ－）在约０．１２Ｖ（ＳＣＥ）处还原，而（ＴＰＰ）Ｃｏ（ＩＩ）（Ｂｒ－）２则在大约Ｃｏ（Ｉ）／Ｃｏ（Ｉ）还原过程出现的更负的电位处发生还原 ; The effect of Br - anion on electrochemical behavior of (TPP)Co was investigated in 1,2 dichloroethane solution by microelectrode and thin layer cyclic voltammetry technique. It was found that the axially coordination of one Br - anion to (TPP)Co(Ⅲ)(Br -) 2 shifts the potential of porphyrin system to more positive value. The reduction peak of 0.12 V(vs.SCE) is attributed to the reduction of (TPP)Co(Ⅲ)(Br -). It is also postulated that the reduction of (TPP)Co(Ⅲ)(Br -) 2 occurred at a more negative potential where the reduction of the Co(Ⅱ)/Co(Ⅰ) process happened. ; 作者联系地址：中国科学院金属腐蚀与防护研究所金属腐蚀与防护国家重点实验室,中国科学技术大学化学系 ; Author's Address: State Key Lab. for Corrosion and Prot., Inst. of Corr. and Prot. of Metals, Chinese Acad.of Sci., Shenyang 110015 Lin Xiangqin Dept. of Chem., Univ. of Sci. and Tec. of China, Hefei 230026$$$
