一实验部分本文以环戊二烯(环丁二烯)镍(Ⅰ)衍生配合物为例,说明其电还原反应电子数的计算方法.实验装置见文献.所有E值都是相对SCE电极而言.电流阶跃实验配合循环伏安实验进行.对于每一个化合物在不同溶剂中进行电流阶跃实验时,选定不同的恒电流值,经4～6次重复实验,分别计算出各次实验电极反应电子数n,然后取其平均值.阴极恒电流数值的选择使得过渡时间τ在5～25秒之间为宜.
An experimental part In this paper, cyclopentadiene (cyclobutadiene) nickel (Ⅰ) derived complexes as an example to illustrate the calculation of the number of electrons in the electronic reduction method.Experimental devices see the literature.Each E value is relative to the SCE electrode and The current step experiment with cyclic voltammetry experiments for each compound in different solvents for current step experiment, the choice of different constant current value, after 4 to 6 times repeated experiments were calculated for each experiment The number of electrode reaction electrons n, and then take the average value of the cathode constant current value makes the transition time τ between 5 ~ 25 seconds is appropriate.
