以2-氨基苯酚和间苯二酚为原料,通过重氮偶合反应合成了2,4,2'-三羟基偶氮苯,并利用红外光谱、核磁分析、电喷雾电离质谱和元素分析对其进行了系统的结构表征;通过主客体物理掺杂方法制备了2,4,2'-三羟基偶氮苯-聚甲基丙烯酸甲酯(PMMA)薄膜;利用紫外-可见吸收光谱分别考察了目标化合物在四氢呋喃(THF)溶液、PMMA薄膜中的光致异构性能,及其在不同极性有机溶剂中异构化的动力学反应.研究结果表明,经365 nm紫外光激发,目标化合物无论在溶剂中还是在聚合物薄膜中都表现出良好的反-顺异构化响应,异构化产率非常高,产物光、热稳定性好,异构反应为一级动力学反应,异构速率常数随着有机溶剂极性增大而减小.
