摘要
用循环伏安法研究了四个npdt和dt的铜(Ⅱ)和镍(Ⅱ)配合物在水溶液中的氧化还原过程,讨论了pH值对npdt的铜(Ⅱ)、镍(Ⅱ)配合物的CV曲线的影响,并测定了两种铜(Ⅱ)配合物在电极表面的异相电子转移反应速率常数,二者的速率常数相近。
By cyclic voltammetry we studied an aqueous oxidation reduction process of four copper(Ⅱ)and Nickel(Ⅱ)complexes containing organic ligands npdt and dt.E1/2 of npdt complexes were independent of pH in the range of 6.0-9.0.The rates of heterophase electron transfer in the surface of electrode were almost the same for two copper(Ⅱ)complexes.
