摘　　要：合成了三种螺萘并噁嗪类光致变色染料:N-甲基-3,3-二甲基螺吲哚啉-2,3'-[3H]萘并[2,1-b][1,4]噁嗪及其6'-位氮杂环取代化合物,并通过1H-NMR、IR表征了它们的分子结构。利用紫外光谱探索了目标产物的光致变色性能。结果表明:随着溶剂极性的增强,其呈色体最大吸收波长发生红移;环上6'-位取代基的电子效应对开环体的光谱性能有明显影响,取代基的给电子性越强,其吸收光谱发生蓝移。Three compounds, called as 1, 3, 3 - Trimethylspiro （indoline - 2, 3＇ - naphtho [ 2, 1 - b] [ 1, 4 ] oxazine）, and 6＇-amino- substituted spiroindolinonaphth [ 2, 1 -b ] [ 1, 4 ] oxazines were synthesized which contains naphthalene ring. The structures weve characterized by 1H-NMR and IR, and the photochromic properties were studied with UV absorption spectrometers. Results showed a red shift of opening absorption peak with the increase of the polarity of the solutions. Besides, 6＇ -substituted elec- tron - donor groups made the maximum absorption wavelength to blue shift.
