摘　　要：合成了Ｅｕ（ＴＴＡ）３Ｌ１（Ⅰ）和［Ｅｕ（ＴＴＡ）３］２Ｌ２（Ⅱ）二种新的铕（Ⅲ）三元配合物（ＴＴＡ＝噻吩甲酰三氟丙酮一价阴离子、Ｌ１＝４，５－二氮芴－９－酮、Ｌ２＝４，５－二氮芴－９－酮连氮）。用元素分析、ＩＲ、ＵＶ和溶液荧光光谱对配合物进行了表征。探讨了溶剂对Ｅｕ（Ⅲ）三元配合物荧光光谱的影响，发现在ＣＨ３ＣＮ中Ｅｕ（Ⅲ）三元配合物发光效果最好。Two Eu(Ⅲ) ternary complexes, Eu(TTA)3 L1(Ⅰ) and [Eu(TTA)3)]2L2(Ⅱ) (where, TTA=thenoyltrifluoroacetonate; L1=4,5diazafluorene9one; L2=4,5diazafluorene9oneazine), have been synthesized. Their compositions and properties were characterized by elemental analysis, IR, UV and solution fluorescent spectra. The effect of solvents on fluorescent intensity have been discussed. The fluorescence intensity of the complexes in CH3CN is higher, but DMF results in the decrease of fluorescence intensity of the complexes.
