合成了一种新型的喹啉衍生物单体-2-苯基喹啉-4-羧酸-丙烯酸-乙二醇二酯（PQFAED）,并通过乳液聚合的方法制备了PQFAED和丙烯酸酯单体（MMA/MAA/BA）的共聚物-P（PQFAED/MMA/MAA/BA）。用IR、UV、GPC、TGA、PGC-MS及荧光光谱表征了单体及共聚物的结构,分析了硝基爆炸物（TNT、RDX及PETN）对该共聚物膜的荧光猝灭作用。结果表明,共聚物薄膜的最大发射波长为436nm,相对于单体的最大发射峰发生了36nm的红移;荧光＂结构自猝灭效应＂,使PQFAED在相同生色团浓度下的荧光强度远低于其相应共聚物的荧光强度;共聚物薄膜对多硝基爆炸物有较好的荧光响应,可作为爆炸物检测的传感材料。

A novel quinoline derivative monomer-2-phenylquinoline-4-formic-acrylic-ethylene glycol diester （PQ- FAED） was synthesized and the copolymer-P（PQFAED/MMA/MAA/BA） was prepared by emulsion eopoly- merization of PQFAED with acrylate monomers （MMA/MAA/BA）. IR, UV, GPC, TGA, PGC-MS and fluo- rescent emission spectroscopy were used to characterize the eopolymer. Furthermore, the fluorescence quench- ing response of nitro-explosives （TNT, RDX and PETN） vapor to copolymer film was investigated. The test results show that the fluorescence maximum wavelength is 436 nm, about 36 nm red-shift comparing to the monomer. Fluorescence ＂structural self quenching effect＂（SSQE） make the fluorescence intensity of PQFAED is dramatically lower than its corresponding copolymer at the same chromophore concentration. The high fluo- rescence response of nitro-explosives to copolymer film was identified, which also indicated that P（PQFAED/ MMA/MAA/BA） film has potential application in nitro-explosives detection.
