摘要 合成了两个新的配合物:[Cu(Phen)(L-Ser)(H2O)]Cl(1)和[Cu(Phen)(L-Tyr)(H2O)]Cl.2H2O(2)(Phen=1,10-邻菲咯啉、L-Ser=L-丝氨酸、-LTyr=L-酪氨酸).用元素分析、摩尔电导率、红外光谱、紫外-可见光谱对配合物进行了表征.分别采用NBT光还原法和循环伏安法测定了配合物的SOD活性及电化学性质.结果表明,这些配合物具有较高的SOD活性,配合物1、2催化O2-.歧化分解速率常数KQ值分别为3.16×107和1.54×107mol-1.L.s-1. Two new complexes FCu(Phen) (L-Ser) (H2O)]Cl (1) and [Cu(Phen) (L-Tyr) (H2O)]Cl·2H2O (2) (Phen=1,10 phenanthroline, L-Ser=L-serine, L-Tyr=L-tyrosine), were synthesized and characterized by elemental analysis, molar conductivity, infrared spectra and UV-vis absorption spectra. The SOD-like activities and electrochemical properties of the complexes have been determined by NBT-illumination method and cyclic voltammetry, respectively. Complexes 1, and 2 have high SOD-like activities, with the KQ values of 3. 16×10^7, and 1.54×10^7mol^-1·L·s^-1, respectively.
