摘要
以苯肼与甲基异丙基甲酮为原料,在浓硫酸催化下制得吲哚,并与相应的碘丙烯进行亲核取代反应生成中间体,然后中间体与1-亚硝基-2-萘酚作用合成N-丙烯基螺恶嗪光致变色化合物,并对其进行了核磁共振和傅立叶红外光谱表征,研究了光致变色性过程和原理。结果表明,采用吲哚与碘丙烯合成了含有双键的吲哚取代物,形成的双键有利于高聚物之间的聚合,提高了光致变色的稳定性,加强了光致变色的效果。N-丙烯基螺恶嗪的分子结构中含有丙烯基双键和恶嗪环两类不同活性的反应官能团,无论作为高性能树脂基体,还是作为其它高性能树脂基体的改性剂,都有广阔的应用前景。
Phenylhydrazine reacted with methyl-3H-indole,which formed 2,3,3-trimethyl-3H-indole under the catalyst of acid.then the indole reacted with corresponding halides.the directly by the bisspironaphthoxazine was synthesized triethylamine.several photochromic compound is synthesized use in indolium halide and nitrosophenol,and been characterized by1H NMR,and UV-VIS spectroscopy in detail.on the basis of spectral data,we research photochromic action of the compound.In this experimentation,It synthesized a kind of indole substituent compound including double bond,which reacted with indole and allyl iodide.The method was innovation.it displaced the old method,which substituted one bond on N-atom in the literature,and the formative double bond was in favor of the polymerization of the polymer and chain extension,enhanced the stability of photochromism,strengthened the effect.It made the experiment excellent.
