采用一种简单的方法在金电极上制备了十二烷基硫醇自组装膜，并在金电极上制备了一个可开关的电极表面。十二烷修饰的电极是电化学惰性的，直到单层被浸泡在1，10-菲咯啉或2，2 '-联吡啶的溶液中。电极的电活性形式可以通过冲洗电极而恢复到非电活性形式。表面红外光谱结果表明，混合单分子膜中同时存在十二烷基硫醇和邻菲咯啉。
A simple method was used to prepare a “switchable” electrode surface by using self-assembled monolayers of dodecanethiol on a gold electrode. The dodecane-modified electrode was electrochemically inactive until the monolayer was soaked in solutions of 1,10-phenanthroline or 2,2‘-bipyridine. The electroactive form of the electrode could be reverted back to the nonelectroactive form by rinsing the electrode. Surface IR results showed that both dodecanethiol and 1,10-phenanthroline exist in the mixed monolayer.
