摘要
以4-溴-1,8-萘二甲酸酐为原料,经亚胺化、酯化等反应,设计合成了一种新的乙烯基荧光功能单体N-甲基丙烯酰氧乙基-4-溴-1,8-萘酰亚胺(NPMA),并用此单体与N-异丙基丙烯酰胺(NIPAAm)通过自由基聚合制备了荧光共聚物PⅠ、PⅡ和PⅢ。采用1 H NMR(核磁共振氢谱)、UV-vis(紫外-可见)光谱和荧光光谱对共聚物的结构及性能进行了表征,结果表明聚合物对金属Pd2+具有高灵敏度的选择性识别作用。
A novel fluorescent functional monomer N-methylacryloxy-ethyl-4-bromoq, 8-naphthalimide （NPMA） was successfully synthesized and copolymerized with N-isopropylacrylamide（NIPAAm） to get a series of fluorescent copolymers（P I , P II and PIII ）. 1 H NMR, UV-vis and fluorescent spectra were used to characterize these polymers. All the results demonstrate that these copolymers have high sensitive and selective fluorometric responses towards Pd^2＋ in aqueous solution, which has potential applications in human health, environmental protection and industrial production.
