| 摘 要： | 用外层单电子快速转移的氧化还原剂二茂铁及其衍生物修饰电极,在电极/溶液界面作为电子传递的中介物,可使电极上进行的慢反应得到加速、起中介催化作用。目前研究较多的是共价键合和高分子膜的修饰,其他方式的修饰报道不多。用能实现分子有序化排列的L-B膜技术进行氧化还原电活性分子的修饰电极还未见报道。我们用L-B膜技术在SnO_2电极上修饰了二茂铁的衍生物-硬脂酸二茂铁酯(FcOCOC_(17)H_(35))双亲化合物,曾研究了修饰膜的电化学可逆行为和稳定性。本文研究硬脂酸二茂铁酯L-B膜修饰的SnO_2电极

| Abstract: | The electrochemical behaviour of SnO_2 electrode modified with L-B films of ferrocenederivative (FcOCOC_(17)H_(35)) has been studied in Fe(CN)_6~(3-/4-) solution. By measuring theelectrochemical kinetic parameters i. e. rate constant of electrode reaction K_s, the chargetransfer mediation of modified molecules at SnO_2/Fe(CN)_6~(3-/4-) interface was analyzed.Decrease in K_s for SnO_2 electrode modified with mono- or multi-layers of ferrocenederivative L-B film indicated that faster electron transfer is expected only in such amodified molecule which can act as a fast charge transfer mediator at SnO_2/Fe (CN)_6~(3-/4-)interface. |
