摘　　要：合成了3种含呋喃丙烯酸酯结构的螺噁嗪类光致变色化合物,通过核磁共振氢谱、红外光谱确认了其结构,并采用滴加Zn2+及掺杂高分子聚甲基丙烯酸甲酯(PMMA)等手段研究了其紫外吸收光谱性能.结果表明,9′-(α-呋喃丙烯酰氧基)螺噁嗪(化合物Ⅲ)具有良好的光致变色性能,动力学分析表明Ⅲc呈色体的光消色反应遵循一级动力学规律.Three 9＇-furanacryloxyspirooxazines are synthesized. The structures of these new compounds are identified by ^1H NMR spectra and IR spectra. Their photochromic behavior is studied on UV- irradiation in the presence of Zn^2＋ and in poly（methlmethacrylate）. The results indicate that compound Ⅲ have shown good photochromic behavior. The analysis results obtained by kinetics show that the photodecoloration of Ⅲ c＇s colored form follows the first-order kinetics.
