Abstract

A novel Cd(II) Coordination Polymer, [Cd(L)₂(SO₄)₂(H₂O)₂][Cd(H₂O)₆]·4H₂O (CP 1) (L = (1,1'-((2,3,5,6-tetramethyl-1,4-phenylene)bis(methylene))bis(4-carboxypyridin-1-ium)chloride)), is prepared and characterized by single-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, infrared spectrum, thermogravimetric analysis, solid-state fluorescence properties and CIE analysis. The single-crystal X-ray diffraction studies reveal that the ligand HLClO₄·H₂O crystallizes in the monoclinic P2₁/n space group, while CP 1 crystallized in the triclinic P-1 space group with two distinct Cd(II) centers. Abundant hydrogen bonds produce the 3D supramolecular structure of CP 1. The experimental results show that the CP 1 has good thermal stability and has potential applications in blue luminescent materials.

Graphical Abstract

含吡啶两性离子配体的Cd(II)配位聚合物的合成、结构表征及荧光性能

制备了一种新型Cd(II)配位聚合物[Cd(L)2(SO4)2(H2O)2][Cd(H2O)6]·4H2O (CP 1) (L =(1,1′-(2,3,5,6-四甲基-1,4-苯基)双(亚甲基))双(4-羧基吡啶-1-ium -氯)))，并通过单晶x射线衍射、元素分析、粉末x射线衍射、红外光谱、热重分析、固态荧光性质和CIE分析对其进行了表征。单晶x射线衍射研究表明，配体HLClO4·H2O在单斜P21/n空间群中结晶，而CP 1在具有两个不同Cd(II)中心的三斜P-1空间群中结晶。丰富的氢键形成了cp1的三维超分子结构。实验结果表明，cp1具有良好的热稳定性，在蓝色发光材料中具有潜在的应用前景。摘要本文合成了一种新型的基于吡啶两性离子配体的Cd (II)配位聚合物单晶。
