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 new dual binuclear copper (Ⅱ) cryptate was synthesized and characterized. The kinetics of reaction between dinuclear copper (Ⅱ) cryptate and O2 was investigated by pulsed radiolysis for the first time. The results show that the copper (Ⅱ) The catalytic rate constant of the cryptate reaches up to 1.89 × 107, and the copper (Ⅱ) cryptate catalyzes the disproportionation of O2 - as the first order reaction.
