摘要
The title complex [Cu（BBA）（NO3）]（NO3）2（BBA = [2-（benzotriazol-1-yl）ethyl][2（benzotriazol-2-yl）ethyl] amine） has been synthesized and structurally characterized.Its crystallizes in triclinic,space group P1 with a = 10.003（3）,b = 11.399（3）,c = 18.186（5）,α = 77.184（4）,β = 88.573（5）,γ = 72.306（5）o,V = 1924.4（9）3,Z = 2,F（000） = 894,Dc = 1.493 Mg/m3,Mr = 865.31,μ = 0.644 mm-1,the final R = 0.0733 and wR = 0.1722 for 4349 observed reflections with I 2σ（I）.Its polyphenol oxidase（PPO） mimic activity was studied spectroscopically by using pyrogallol as the substrate.The results showed that the kinetics of pyrogallol catalyzed by the complex obeyed the Michaelis-Mentent equation,showing that the PPO catalytic activity of the complex increased with increasing the reaction temperature and pH values.
