摘要
金基底上的硫醇自组装单分子层膜（Ｓｅｌｆ－ａｓｅｍｂｌｅｄｍｏｎｏｌａｙｅｒｓ，ＳＡＭｓ）具有良好的稳定性和有序性，因此在基础研究及应用技术等领域都受到了广泛的重视［１］．通过电化学方法测定自组装膜对溶液中电活性物质的异向电子转移的阻碍作用，可以非常...
The self assembled monolayers(SAMs) of octadecanethiol and dodecylthiol are prepared. Its electrochemical behaviors in the solution of Fe(CN) 3- 6/Fe(CN) 4- 6 with various concentrations are investigated by electrochemical impedance spectroscopy and cyclic voltammetry technology. Although there are no diffusion behavior in CV and EIS results, comparing with the theoretical results, it can be induced that there may be some collapsed or loosely packed sites (defects) in monolayers which provide a mechanism for rapid electron transfer.
