以2‐噻吩乙醛酸（HL）为第一配体，红菲绕啉（Bath）为第二配体合成了一种新型Eu（Ⅲ）三元配合物．采用等离子体原子发射光谱（ICP）、元素分析、FT‐IR和1 H NMR表征了配合物的组成及结构．通过热重（TG）和发光光谱研究了配合物的热稳定性与发光性能．结果表明，该配合物分子式为EuL3 Bath?2H2 O ，具有良好的热稳定性．在最佳激发波长（270 nm ）的紫外光照射下，该配合物能发出Eu （Ⅲ）离子很强的特征红光，其中电偶极跃迁（5 D0→7 F2，613 nm ）发射最强；此外，该配合物还表现出相对较长的衰减寿命（τ＝11．7 m s ）．

A novel ternary europium complex was synthesized with the first ligand of 2‐thio‐pheneglyoxylic (HL) and the secondary one of bathophenanthroline (Bath) .Its composition and structure were characterized by means of inductively coupled plasma atomic emission spec‐trometer (ICP) ,elemental analysis ,FT‐IR and 1 H NMR .The thermostability and lumines‐cence properties of the complex were investigated by TG and emission spectrum .The results indicates that the complex have the molecular formula EuL3 Bath?2H2 O and show s good ther‐mostability .Meanwhile ,the complex can emit strong red light under irradiation at the optimal excitation wavelength (270 nm) .Among them ,the strongest emission band of Eu(Ⅲ) at 613 nm belongs to electric dipole transition (5 D0 → 7 F2 ) .In addition ,the complex possesses com‐paratively longer decay lifetime (τ= 1 1.7 ms) .
