合成了一个新的β-二酮配体1-(2-噻吩基)-3-(对苯乙炔基苯基)-1,3-丙二酮(HTPP), 并用HTPP、邻菲罗啉(phen) 分别与Eu(III)和Tb(III)反应, 生成了两个新的三元稀土配合物Eu(TPP)3phen和Tb(TPP)3phen, 用红外光谱、化学分析、元素分析及热重分析对它们的组成和结构进行了表征. 室温下, 在紫外光激发下Eu(III)和Tb(III)的配合物表现出中心离子的特征荧光发射, 发现β-二酮配体对配合物的荧光有较大影响, 通过量子化学计算从理论上对实验结果进行了解释.

A new β-diketone ligand 1-(2-thienyl)-3-(p-phenylethynylphenyl)-1,3-propanedione (HTPP) was designed and synthesized. Both Eu(TPP)3phen and Tb(TPP)3phen have been synthesized by the reaction of HTPP and 1,10-phenanthroline (phen) with Eu(III) and Tb(III) respectively and characterized by IR spectra, chemical analysis, elemental analysis and thermogravimetric analysis. At room temperature, under UV light excitation, the Eu(III) and Tb(III) complexes exhibited characteristic emission of the central ions. It was found that HTPP ligand had significant effect on the luminescent property of the rare earth complexes, which was interpreted by quantum chemistry calculation.

Key words: β-diketone, lanthanide complex, luminescent property
