摘　　要：合成了３个由—ＮＨＣＯ（ＣＨ２）ｎＣＯＮＨ—链连接的双螺萘并嗪光致变色化合物，经红外光谱，核磁共振氢谱和元素分析确证了其结构，并对它们在聚苯乙烯薄膜中的吸收光谱和光致变色性能进行了测试。结果表明：双螺嗪化合物有色态的吸收光谱明显红移，其稳定性显著提高，８°Ｃ下螺嗪化合物有色态的暗退色反应遵循两种不同的动力学过程。Three kinds of bisspironaphthoxazine linked via—NHCO(CH_2)nCONH—chain:bis[5{1,3,3-trimethylspiro(indoline-2,2′naphthoxazine)}]α,ωsuccinylamide (BSO1),bis[5-{1,3,3-trimethylspiro(indoline-2,2′naphthoxazine)}]α,ωadipoylamide(BSO2),bis[5-{1,3,3-trimethylspiro(indoline-2,2′naphthoxazine)}]α,ωazelaylamide(BSO3) were synthesized and certified by IR,1HNMR and element analysis.Their absorption and photochromic behavior in polystyrene film were also investigated.It shows that the adsorption of their coloured forms has redshift effects and the stability of photomerocyanine has been increased.The better planarity for BSO1 made a higher stability for its colored forms.
