我们证明了电子从钽酸盐纳米片的导带转移到钨酸盐纳米片的导带取决于在由硫醇接枝的钽酸盐纳米片和烯烃接枝的钨酸盐纳米片的硫醇-烯点击反应制备的交替堆叠结构中的层间距离。通过改变有机桥的亚甲基链数，层间距被精确地控制在0.93 ~ 1.64 nm之间。电子转移速率常数的对数随距离的增加而线性减小。
We demonstrate the electron transfer from the conduction band of tantalate nanosheets to that of tungstate nanosheets depending on the interlayer distance in the alternate-stacked structure prepared by the thiol-ene click reaction of thiol-grafted tantalate nanosheets and alkene-grafted tungstate nanosheets. The interlayer distance is precisely controlled from 0.93 to 1.64 nm by changing the methylene chain number of the organic bridges. The logarithm of the rate constant of the electron transfer decreases linearly with the distance.
