Abstract

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 1HNMR.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.
