为了寻找新的发光材料并研究β-二酮对稀土配合物发光性能的影响, 我们合成了一个新的β-二酮配体: 1-苯 基-3-(对苯乙炔苯基)-1,3-丙二酮(HPPP), 并用HPPP、邻菲罗啉(phen)分别与Eu(III)和Tb(III)反应, 合成了两个新的三元稀土配合物: Eu(PPP)3phen和Tb(PPP)3phen, 通过红外光谱、化学分析、元素分析对三元稀土配合物的组成和结构进行了表征. 研究了配合物的荧光性质, 发现β-二酮配体对配合物的发光有较大影响, 通过量子化学计算对实验结果进行了解释.

In order to seek new luminescent materials and study the effects of β-diketone on the luminescence property of rare earth complexes, a novel β-diketone ligand 1-phenyl-3-(p-phenylethynylphenyl)- 1,3-propanedione (HPPP) was designed and synthesized. Both Eu(PPP)3phen and Tb(PPP)3phen have been synthesized by the reaction of HPPP and 1,10-phenanthroline (phen) with Eu(III) and Tb(III) respectively and characterized by IR spectra, chemical analysis and elemental analysis. The study on luminescence properties of the complexes finds that HPPP ligand has significant effects on the luminescence property of the rare earth complexes, which were interpreted by quantum chemistry calculation.

Key words: β-diketone, rare earth, ternary complex, luminescence proper
