合成了2个三元甘氨酰甘氨酸-铜(Ⅱ)-多吡啶型配合物:[Cu(Gly-gly)(DPPZ)]·2H2O(1)和[Cu(Gly-gly)(TATP)]·2H2O(2)(Gly-gly=甘氨酰甘氨酸,DPPZ=二吡啶并[3,2-a;2,3-c]吩嗪,TATP=1,4,8,9-四氮三联苯),并由元素分析、红外光谱、紫外-可见光谱以及摩尔电导率测定对其进行了表征。应用改进的氯化硝基四氮唑蓝光照还原法研究了这些配合物及[Cu(Gly-gly)(Phen)]·3H2O(3)(Phen=1,10-邻菲咯啉)在水溶液中催化超氧阴离子自由基(O2.-)歧化分解(SOD)的活性,用循环伏安法研究了配合物的电化学性质。结果表明,3种配合物均具有良好的SOD活性,表观催化速率常数分别为1.08×107,1.11×107和1.20×107L/mol·S。
Two (3) glycosylglycine-copper (Ⅱ) -polypyridyl complexes [Cu (Gly-gly) · 2H2O (1) and [Cu (Gly-gly) · 2H2O (2) (Gly-gly = glycylglycine, DPPZ = dipyrido [3,2-a; 2,3-c] phenazine, TATP = 1,4,8,9-tetraaza-terphenyl ), And characterized by elemental analysis, IR, UV-Vis and molar conductivity. The complexes of Cu (Gly-gly) (Phen)] · 3H2O (3) (Phen = 1,10-phenanthroline) were studied in the aqueous solution by the improved nitroblue tetrazolium blue photoluminescence (O2.-) disproportionation (SOD) activity of the catalyst, the electrochemical properties of the complex was studied by cyclic voltammetry. The results showed that all the three complexes had good SOD activity and the apparent catalytic rate constants were 1.08 × 107, 1.11 × 107 and 1.20 × 107L / mol · S, respectively.
