α-烯丙基取代β-二酮类化合物的合成及其稀土配合物发光性能的研究

Study on the Synthesis of α-Allyl-β-Diketones and Photoluminenescence of Rare Earth Complexes

合成了α-烯丙基二苯甲酰甲烷(ADBM)和α-烯丙基乙酰丙酮(APD)两种配体及其铕、铽的三元稀土配合物,通过红外、元素分析确定了配合物的组成、结构.运用紫外和荧光光谱讨论了烯丙基的引入对配合物发光性能的影响.

2-allyl-1,3-dibenzyl-1,3-propdione( ADBM) and 3-allyl-2,4-pentanedione (APD )are synthesized.Meanwhile,the rare earth complexes having the compositionsof Eu(L)3phen ,Tb(L)3phen (L1=acac,L2=APD,L3=DBM,L4=ADBM) are synthesized and characterized by FTIR spectra and elemental analysis.UV spectra and photoluminenescence spectra have been investigated.The results show that allyl which is added to the complexes has obvious influence on the PL efficiency of complexes.
