| 摘 要： | 将甲基丙烯酸N，N-二甲氨乙酯（DMAEMA）和微量荧光单体4-丙烯酰氧基四苯乙烯（TPE-a）经自由基共聚合制备了共聚物Poly（DMAEMA-co-TPE-a）（PDT），并通过引入交联剂N，N-亚甲基双丙烯酰胺（Bis）和致孔剂N，N-二甲基甲酰胺（DMF）制备了pH敏感荧光多孔光纤。采用FT-IR、1H-NMR、TG和SEM表征了产物的结构，研究了产物的荧光和pH响应性能。研究表明，共聚物PDT具有聚集诱导发光（AIE）效应，并具有较好的pH响应性能；当单体、交联剂和致孔剂的物质的量之比为60：1：40时，制备的pH敏感荧光多孔光纤具有较好的耐热性能、内部结构和pH响应性能。

| Abstract: | Poly(DMAEMA-co-TPE-a)(PDT) was synthesized by radical copolymerization of N-(2-(dimethylamino)ethyl)-methacrylamide(DMAEMA) and trace fluorescent monomer 4-acryloyl tetraphenylethylene (TPE-a).The pH-sensitive fluorescent porous fiber was then prepared via introducing cross-linking agent methylene-bis-acrylamide(Bis) and porogenic agent N,N-dimethylformamide(DMF) into the system.The products were characterized by FT-IR,1H-NMR,TG and SEM.The fluorescent property and pH-response performance of products were also studied.Results show that PDT owns aggregation-induced emission(AIE) effect and good pH-response performance.When the molar ratio of monomer,cross-linking agent and porogenic agent is 60:1:40,the obtained fiber showed a satisfing heat-resistant quality and pH-response performance. |
