摘　　要：目的研究小分子配合物5-丁氧甲基-8-羟基喹啉丙烯酸铽及其与苯乙烯聚合的高分子配合物的发光性能和热性能,并探讨聚合时间对高分子配合物性能的影响。方法通过氯甲化反应和取代反应合成5-丁氧甲基-8-羟基喹啉(BTMQ),并以BTMQ和丙烯酸(HAA)为配体合成5-丁氧甲基-8-羟基喹啉丙烯酸铽(Tb(BTMQ)2HAA)。然后,用小分子配合物和苯乙烯聚合得高分子配合物p(St-coTb(BTMQ)2HAA。通过热重(TG)分析和荧光光谱测试研究配合物的热性能和发光性能。结果小分子配合物的起始分解温度和荧光强度分别为262℃和222;聚合反应为8 h时,高分子配合物的起始分解温度和荧光强度均最大,分别为380℃和228。结论高分子配合物比小分子配合物具有更好的热性能和发光性能,最佳聚合反应时间为8 h。The paper aims to study luminescent property and thermal property of small molecular complex of 5-butyloxymethyl-8-hydroxyquinolin terbium acrylate and its polymer complex with styrene polymer, and discuss effects of polymer time on properties of polymer complex. 5-butyloxymethyl-8-hydroxyl-quinolin(BTMQ) was synthesized by chloromethylation reaction and substitution reaction, and the small molecular complex of 5-butyloxymethyl-8-hydroxyquinolin terbium acrylate(Tb(BTMQ)2HAA) was synthesized with BTMQ and acrylic acid(HAA) as ligands. And then, the polymer complex of p(St-co-Tb(BTMQ)2HAA) was prepared by polymerization of small molecular complex and styrene. The thermal property and luminescent property were investigated by thermogravimetric(TG) analysis and determination of fluorescence spectrum. The initial decomposition temperature and fluorescence intensity of small molecular complex were 262 ℃ and 222 ℃, respectively. When the polymerization time was 8 h, the initial decomposition temperature and fluorescence intensity of the polymer complex were the highest, 380 ℃ and 228 ℃,respectively. The Polymer complexes have better thermal and luminescent properties than small molecular complexes. The best polymerization time is 8 h.
