A Cadmium Complex Assembled with Tris[p-(4-pyridylvinyl)phenyl]amine: Synthesis, Crystal Structure and Luminsecent Sensing Property

以三[p-(4-吡啶乙烯基)苯基]胺(L)和1,3-二(4-羧基苯基)苯(H 2bcb)为配体,采用水热法合成了1个结构新颖的镉配位聚合物{[Cd(L)(bcb)]}n(1),并通过单晶X单晶衍射分析、红外光谱分析、元素分析和热重分析对其结构进行了表征。单晶结构分析表明配合物1属于三斜晶系,空间群为C2/c。配合物1形成了二维网状结构,分子中的Cd(Ⅱ)离子采取七配位模式,形成了十面体配位构型。荧光传感实验表明配合物1对2,4,6-三硝基苯酚检测具有高度的灵敏性和选择性。

A new coordination compound{[Cd(L)(bcb)]}n(1)(L=tris[p-(4-pyridylvinyl)phenyl]amine,H 2bcb=1,3-bi(4-carboxyphenyl)benzene)was synthesized by hydrothermal method and characterized by single-crystal X-ray diffraction,infrared spectroscopic analysis,elemental analysis and thermogravimetric analysis.The crystallofraphic a nalysis revealed that 1 crystallizes in monoclinic crystal system with a space group of C2/c and exhibited a 2D network structure.The Cd(Ⅱ)ion in the molecule adopts a seven-coordinated pattern,forming a slightly twisted decahedral coordination configuration.The fluorescence sensing experimtents indicated that 1 exhibits fluorescence quenching to 2,4,6-trinitrophenol with high sensitivity and selectivity.
