摘要
以1,3,3-三甲基-2-亚甲基吲哚啉和1-亚硝基-2-萘酚为原料合成了N-甲基-3,3-二甲基螺吲哚啉-2,3’[3H]萘并[2,1-b][1,4]噁嗪,对其进行了紫外和红外光谱以及元素分析,并对其光致变色性质以及主要影响因素温度、溶剂和pH进行了研究。结果表明,该化合物具有良好的光致变色性和一定的酸致变色性;温度、溶剂极性和pH对其光致变色性有不同程度的影响。
N - Methyl - 3,3 - dimethyl spiroindoline - 2,3＇ [ 3 H ] naphthaline [ 2,1 - b ] [ 1,4 ] oxazine was synthesized by 1,3,3 - tri- methyl -2 -methylene indoline and 1 -nitroso- 2 -naphthol, its UV and IR spectra and elemental analysis were carried out, and the photochromism and main influencing factors such as temperature, solvent and pH were studied. The result showed that the compound was of good photochromism and certain acidichromism; temperature, the polarity of solvent and pH had different effect on its photochromism.
