摘要
研究了一种可作为聚合物类光折变材料中半功能型的基体材料——聚乙烯侧基含偶氮对硝基苯。以聚乙烯咔唑和偶氮盐为原料,以十二烷基苯磺酸钠为相转移催化剂,通过后重氮偶合方法,制备出聚乙烯咔唑侧基含生色团偶氮对硝基苯。用IR、UV-v is、1H-NM R、GPC对聚合物偶合前后进行了分析和表征。IR、UV-v is、1H-NM R测试表明了偶氮苯已经接到咔唑环上。UV-v is结果表明偶合反应时间对聚合物的偶氮含量有很大的影响。GPC结果表明,聚合物与重氮盐偶合后,分子量增大。
Polymer（N-vinyl carbazole） containing （p-nitrophenyl）azo as bi-functional matric in polymeric photorefractive material was studied in this paper. Poly（N-vinyl carbazole）containing （p-nitrophenyl） azo was synthesized by post-azo-coupling reaction using sodium dodecylben- zenesulphonate as phase-transfer catalysts, Its coupled product was analyzed by IR, UV-vis, ^1H- NMR and GPC techniques. The IR, UV-vis and ^1H-NMR measure indicates that diazo has been grafted to carbazole. The test of UV-vis also manifests that the influence of coupling time on diazo content is great. The result of GPC indicates that molecular weight has been raised after polymer coupling.
