设计、合成了半刚性双齿配体1，4-双{[（2′-吡啶甲氨基）苯氧基]甲基}-2，5-双甲苯（L），并将其作为构筑发光镧系聚合物的结构单元.通过元素分析、X射线衍射和红外光谱对两种新的稀土配位聚合物进行了表征。配位聚合物的金属与配体的摩尔比为1：1，半刚性双齿配体桥连镧系硝酸盐形成锯齿形链，并通过C-H···O氢键相互作用形成三维超分子结构.详细讨论了铕（III）配合物的发光性质。
The semirigidexo‐bidentate ligand 1, 4‐bis{[(2′‐picolylaminoformyl)phenoxyl]methyl}‐2, 5‐bismethylbenzene (L) was designed, synthesized, and used as building blocks for constructing luminescent lanthanide polymers. Two new lanthanide coordination polymers were characterized by elemental analysis, X‐ray diffraction analysis, and IR spectroscopy. The coordination polymers exhibit the metal‐to‐ligand molar ratio of 1:1 and the semirigidexo‐bidentate ligand bridges lanthanide nitrates forming a zigzag chain, which further interconnected to three dimensional supramolecular structure in aid of cooperative C–H···O hydrogen bonds. The luminescence properties of the europium(III) complex are discussed in detail.
