超薄层有机材料的制备与研究￣［１］受到人们的广泛关注，有关研究结果和进展正在不断丰富着人类对表面结构与性质关系的理解和认识。与其它制备单分子层的技术相比，自组装技术是一种较新的制备方法，在８０年代后期，迅速成为有关学科的研究焦点。采用此技术制备的超薄层体系主要有两类：一类是巯基化合物在金、银、铜、铂表面吸附形成的单层￣［２，３］，一类是在硅、玻璃、金属氧化物表面通过硅烷化反应形成的单层￣［４］。其中，硫醇类分子自组装单层（ｓｅｌｆ－ａｓｓｅｍｂｌｅｄｍｏｎｏｌａｙｅｒ，３ＡＭ）是被研究得最为广泛和深入的体系。本文主要综述十年来巯基化合物ＳＡＭ的研究进展。
The preparation and research of ultrathin layers of organic materials [1] have drawn extensive attention. The research results and progress are continuously enriching human understanding and understanding of the relationship between surface structure and properties. Compared with other techniques for preparing monolayers, self-assembly technique is a relatively new method of preparation. In the late 1980s, self-assembly technique rapidly became the focus of the relevant disciplines. There are two main types of ultrathin layer systems prepared by this technique: one is the monolayer formed by the adsorption of mercapto compounds on the surface of gold, silver, copper and platinum [2,3], the other is the oxidation of silicon, glass and metal The surface of the monolayer formed by the silanization reaction [4]. Among them, self-assembled monolayers (3AM) of thiol molecules are the most extensively studied and in-depth systems. This article summarizes the research progress of sulfhydryl compounds SAM in ten years.
