摘要
合成了4个新的配合物:[Cu(Phen)(L-Phe)(H2O)]Cl·2H2O、[Cu(Phen)(Gly)(H2O)]Cl·2.5H2O、[Cu(Phen)(L-Arg)(Cl)]Cl·2.5H2O、[Cu(Phen)(L-Ile)(H2O)]Cl·2H2O(Phen:1,10-邻菲咯啉;L-Phe:苯丙氨酸;Gly:甘氨酸;L-Arg:精氨酸;L-Ile:异亮氨酸).用元素分析、红外光谱、紫外-可见光谱、热重等方法对配合物的结构进行了表征,并用改进的氯化硝基四氮唑蓝(NBT)光还原法测定了这4个配合物催化歧化超氧阴离子(O2^-)的能力.结果表明,这些配合物在10^-8~10^-7mol·L^-1的浓度范围内对NBT光还原速率均能达到50%以上的抑制率.
Four new complexes of Cu(Ⅱ ) with phenanthroline and L-amino acid (L-Phenylaninate, Glycinate,L-Argininate,L-Ileucinate) were synthesized and characterized by elemental analysis, infrared spectra, UV-vis absorption spectra and thermal gravimetric analyses. The catalytic activity of the complexes for the disproportionation of O2 ^ - was determined by NBT method. The result shows that the complexes have a high SOD-like activity, and their concentrations of 50% inhibition are in the range of 10^-8~10^-7mol·L^-1.
