摘　　要：利用β-二酮烃基化反应合成了一种配体3-苄基-2,4-戊二酮(BPD),用红外光谱与核磁共振谱对产物的结构进行确定。以BPD为第一配体和邻菲罗啉(Phen)为第二配体,与稀土铕离子制备了配合物,并对其C,H,N的组成百分比按实验分子式[Eu(BPD)3Phen或EuC48H50N2O6]作了测定和计算。并用红外光谱和紫外-可见吸收光谱法对配体进行表征,并用荧光光谱检测其荧光发光性能。3-Benzyl-2,4-pentanedione （BPD） was synthesized by alkylation of 2,4-pentanedione with benzyl chloride, and its molecular structure and composition were identified by IR-spectrometry and 1 HNMR. A ternary coordination compound of Eu3＋ with BPD as 1st ligand and 1,10-phenanthroline （Phen） as 2nd ligand was prepared, and % composition of C, H and N in the product was determined and calculated according to the empirical formula Eu（BPD）3Phen or EuC48H50N2O6. Absorption spectrum and fluorescence emission spectrum of the coordination compound were studied respectively by IR-spectrometry, UV-VIS-spectrophotometry and fluorescence spectrometry.
