摘要
偶氮苯衍生物既具有偶氮苯基团的光致顺反异构化活性，又具有优异的力学性能和加工性能，在液晶材料、光信息存储材料及非线性光学材料等许多领域都具有广泛的应用，近年来引起了研究工作者极大的关注。文章综述了偶氮苯衍生物的顺反异构机理，总结了偶氮苯衍生物在光学方面的应用及发展状况，最后提出了对其发展前景的展望。
Azobenzene derivatives have both photo-responsive cis-trans isomerization, excellent mechanical properties and processing performance, which showed wide applications in many areas, such as liquid crystal materials, optical in- formation storage materials, and nonlinear optical materials. The related research had aroused great attention of many re- searchers in recent years. The mechanism of cis-trans isomerization, the related performance and application, the future prospects of the development of azobenzene derivatives summarized and discussed.
