合成了配合物[Cu(NTB)Cl]ClO4.2.5CH3OH(NTB为N,N,N-三(2(-苯并咪唑甲基)胺),并进行了紫外可见光谱、元素分析、循环伏安和单晶X射线衍射分析等表征.用UV-Vis.研究了以邻苯二酚、邻苯三酚为底物时配合物的多酚氧化酶活性,结果表明:配合物的多酚氧化酶活性符合米氏方程曲线;在pH为8.0和30℃的条件下,配合物催化邻苯三酚和邻苯二酚反应的转化数分别为88.2 h-1和0.54 h-1.通过动力学数据比较发现,邻苯三酚比邻苯二酚更容易氧化,而且它们的催化氧化速率都随着pH的升高而增大. The complex Cu (NTB) Cl] ClO4.2.5CH3OH (NTB is N, N, N - tris (2 - benzimidazolylmethyl) amine) was synthesized and characterized by UV - visible spectroscopy, elemental analysis, Anne and single crystal X-ray diffraction analysis, etc. The polyphenol oxidase activity of the complex with catechol and pyrogallol as substrates was studied by UV-Vis. The results showed that the polyphenol oxidase The results showed that the conversion of pyrogallol and catechol catalyzed by the complex was 88.2 h-1 and 0.54 h-1, respectively, at pH 8.0 and 30 ℃ .According to the kinetics The data found that pyrogallol oxidized more easily than catechol, and their catalytic oxidation rates increased with increasing pH.
