摘　　要：合成了一种含杂芴基的β-二酮配体2-(3-对氯苯基-1,3-丙二酮基)-二苯并噻吩(HL),通过核磁共振谱,红外光谱和质谱对其进行了表征.以HL为配体与Eu^(3+)分别合成了它们的二元、三元配合物,并通过荧光光谱、差热-热重分析和红外光谱对配合物进行了表征及发光性质研究.通过荧光分析表明:Eu^(3+)的配合物的发光主要发出613 nm处的特征红光,表明配体很好地敏化了Eu^(3+)离子的发光.通过引入第二配体(1,10-邻菲咯啉或2,2'-联吡啶),配合物的荧光强度明显增强.通过在EuL_3·phen中掺入Sm~^(3+)离子,发现适量的掺杂能更好地敏化Eu^(3+)离子的发光.A β - diketone ligand with heterofluorene group （ HL ）, 2 - （ 3 - p - chlorophenyl - 1,3 - oxopranoyl）-dibenzothiophene, was synthesized, and its chemical structure was confirmed by nuclear magnetic resonance spectroscopy, infrared spectroscopy and mass spectrum. Its binary and ternary Eu （Ⅲ） complexes were prepared. And their structures and luminescent properties were investigated by fluorescence spectra, TG-DTA and IR. By fluorescence analysis showed that the Eu（Ⅲ） complexes emit strong red light peaking at 613 nm and the ligand sensitize the luminescence of Eu（Ⅲ） ion well. By introducing a second ligand （1,10-phenanthroline or 2,2＂-bipyridine）, the fluorescence intensity of the complexes is significantly enhanced. By the incorporation of a reasonable amount of Sm3＋ ions in EuL3· phen, the luminescence of Eu（Ⅲ） ion can be sensitized better.
