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。
At present, the research on materials is developing more and more in the direction of precision and control. The research on field-sensitive materials is increasingly becoming a research hotspot. Azobenzene and its derivatives have reversible photoisomerization under ultraviolet-visible light irradiation. Therefore, research on azobenzene sensitive membrane materials is increasingly becoming a hot spot. First of all, the phenomenon of the photoisomerization of azobenzene molecules and the change of their properties during the isomerization process are introduced. Then many factors that affect the photo-induced rate of azobenzene molecules are described in detail. Finally, the self-assembled monolayers of azobenzene derivatives Applications in optics, surface chemistry, chemical separation and biomedicine.
