24元环双核铜（Ⅱ）配合物的合成及其对超氧化物歧化酶的模拟──Ⅲ．配合物的电化学研究

SYNTHESIS OF FOUR 24-MEMBERED MACROCYCLIC BINUCLEAR COPPER(Ⅱ)COMPLEXES AND MODELLING ON SUPEROXIDE DISMUTASE

由２，６－二乙酰基吡啶与３－氧杂戊烷１，５－二胺缩合成大环配体，首次用循环伏安法研究了在水溶液中它与铜（Ⅱ）生成以Ｈ２Ｏ，ｉｍ－，Ｎ－３和ＳＣＮ－为桥联的双核配合物的氧化还原过程，探讨了两中心原子间的作用，联系配合物歧化活性提供的信息，从电化学角度解释了活性实验的结果。

For the first time an aqueous oxidation-reduction process of binuclear copper(Ⅱ) complexes,in which two metal centers liked in via H2O2im-,N3-,SCN-bridge has been studied by cyclic voltammetry.Macrocyclic ligand was synthesized by condensation of 2,6-diacetylpyridine with 3-oxapentane-1,5-diamine.The interaction between two central atoms in complexes was investigated.The activity of complexes was explained according to electrochemical results.
