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请下载后查看，本文暂不支持在线获取查看简介。(3+)离子,发现适量的掺杂能更好地敏化Eu~(3+)离子的发光.
A kind of β-diketone ligand 2- (3-p-chlorophenyl-1,3-propanedionato) -dibenzothiophene (HL) was synthesized by NMR spectroscopy and Fourier transform infrared spectroscopy And their spectra were characterized.The binary and ternary complexes of them were synthesized by using HL as ligand and Eu ~ (3+) respectively, and their complexes were characterized by fluorescence, DTA-TG and IR spectra The results show that the luminescence of the Eu 3+ complex mainly emits characteristic red light at 613 nm, which indicates that the ligand sensitizes the Eu 3+ ion The fluorescence intensity of the complex was significantly enhanced by the introduction of the second ligand (1,10-phenanthroline or 2,2’-bipyridine) This article does not support online access to view profile. (3+) ions, we found that the appropriate amount of doping can better sensitize the luminescence of Eu 3+ ions.
