摘　　要：目前,材料的研究越来越朝着精密可控的方向发展,对外场敏感材料的研究日益成为研究的热点。偶氮苯及其衍生物具有在紫外-可见光照射下发生可逆光致异构化的特性,因而偶氮苯类敏感膜材料的研究日益成为研究的热点。首先介绍偶氮苯分子光致异构现象及异构化过程中性能的变化,然后详细阐述了影响偶氮苯分子光致速率的诸多因素,最后综述了国内外偶氮苯衍生物自组装膜在光学、表面化学、化学分离及生物医药等领域的应用研究进展。Recently, the research on materials focuses on precision and controllable, and materials which are sensitive to external fields have become the research hot spot. Because of the reversible photoisomerization characteristics of azohenzene and its derivates under UV-Vis irradiation, the azohenzene self-assembly monolayers （SAMs） is attracting much more attentions of researchers. The photoisomerization and the varieties of performances during the photoisomefization process of azobenzene molecules are introduced. Then the factors which have effects on the photoisomerization rate of azobenzene are detailed. At last, the applications and research progress of azobenzene self-assembly monolayers in the many fields at home and abroad are summarized, such as optics, surface chemistry, chemical separation and biological medicine pharmacy, etc.
