以2,2′-联吡啶-3,3′-二羧酸为配体合成了一个稀土-有机功能配合物[Tb2(C12H6O4N2)3(Phen)2(H2O)2.6H2O]n,并用X射线单晶衍射仪测定了其结构。检测了该配合物的荧光和磁性。结果表明:配合物在490.0、546.0、586.0和620.0nm处有四个特征荧光发射峰,它们分别归属于铽(Ⅲ)离子的5D4→7F6,5D4→7F5,5D4→7F4和5D4→7F3的电子跃迁;在低温下配合物有弱的反铁磁性。
A rare earth-organic functional complex [Tb2 (C12H6O4N2) 3 (Phen) 2 (H2O) 2.6H2O] n was synthesized from 2,2’-bipyridine-3,3’-dicarboxylic acid and X-ray Single crystal diffractometer measured its structure. The fluorescence and magnetic properties of the complex were tested. The results show that the complexes have four characteristic fluorescence emission peaks at 490.0,546.0,586.0 and 620.0 nm, which belong to the 5D4 → 7F6, 5D4 → 7F5, 5D4 → 7F4 and 5D4 → 7F3 electrons of terbium (Ⅲ) ions, respectively Transition; at low temperatures complexes have weak antiferromagnetic.
