摘　　要：合成并表征了一个全新的双核铜 (Ⅱ )穴合物 ,并首次利用脉冲辐解法来研究双核铜 (Ⅱ )穴合物 (SOD模型物 )与O2 反应动力学 ,结果表明该铜 (Ⅱ )穴合物的催化速率常数可达 1 .89× 1 0 7,铜 (Ⅱ )穴合物催化歧化O2 - 为一级反应。A novel binuclear copper(Ⅱ) cryptate (SOD model compound) was synthesized and characterized in detail . Using pulse radiolysis, the kinetics and mechanism of catalytic dismutation of O_2^- by the copper(Ⅱ)cryptate were studied.The catalytic rate constant was 1.89×10~7。The catalytic mechanism of cryptate was a first-grade reaction with regard to O_2^-.
