摘　　要：基于Eu(Ⅲ)配合物的圆偏振发光材料在三维显示和生物响应成像等领域中引起了广泛的关注,我们设计并报道了一对羧基化2,2′-联吡啶手性配体((+)-L和(-)-L)的合成。通过与高发光效率的β-二酮Eu(Ⅲ)配合物[Eu(TTA)3]·2H2O(TTA=2-噻吩甲酰三氟丙酮)反应,可以分别得到一对手性双核Eu(Ⅲ)对映体[Eu2((+)-L)2(TTA)2(C2H5OH)2]((+)-1)和[Eu2((-)-L)2(TTA)2(C2H5OH)2]((-)-1),并通过单晶X射线衍射测定了(+)-1的结构。我们研究了(+)-1和(-)-1的吸收、发射和手性光谱学性质,能够清晰地检测到圆偏振发光活性。Circularly polarized luminescence materials based on emissive Eu(Ⅲ) complexes have attracted considerable attention in 3D-displays and bioresponsive imaging.In this work,we design and report the syntheses of a pair of chiral carboxylic-containing 2,2′-bipyridine ligands((+)-L and(-)-L).Through reaction with highly emissiveβ-diketone Eu(Ⅲ) complexes[Eu(TTA)3]·2H2O(TTA=2-thenoyltrifluoroacetone),a couple of chiral dinuclear Eu(Ⅲ) enantiomers,[Eu2((+)-L)2(TTA)2(C2H5OH)2]((+)-1)and[Eu2((-)-L)2(TTA)2(C2H5OH)2]((-)-1),were prepared,and the structure of(+)-1 was confirmed by single-crystal X-ray diffraction.The absorption,emission and chiroptical properties of(+)-1 and(-)-1 were investigated,and distinct CPL activities were clearly detected.CCDC:1916754,(+)-1.
