摘要: 以硝酸锌、吡嗪-2,3,5,6-四羧酸为原料,采用溶剂热法成功制备了一种新型锌基配合物Zn2(H2PZTC)2·0.08DMSO·4C2H7N·2H2O(配合物1,H4PZTC=吡嗪-2,3,5,6-四羧酸,C8O8N2H4, DMSO=二甲基亚砜, C2H6SO),并通过单晶X射线衍射、粉末X射线衍射、红外光谱和热重分析对其结构进行了表征。配合物1中的锌离子通过质子化的吡嗪-2,3,5,6-四羧酸形成了两种二级建筑单元,各建筑单元交错排列形成了二维层状结构,并借助氢键弱作用形成三维超分子结构。荧光性能的研究结果表明Fe3+与配合物1之间存在竞争吸收,所以配合物1对Fe3+表现出良好的荧光猝灭效果和较低的检测限。

Abstract: A novel zinc-based complex, Zn2(H2PZTC)2·0.08DMSO·4C2H7N·2H2O (complex 1,H4PZTC=pyrazine-2,3,5,6-tetracarboxylic acid, C8O8N2H4, DMSO=dimethyl sulfoxide, C2H6SO), was successfully synthesized via the solvothermal method using zinc nitrate and pyrazine-2,3,5,6-tetracarboxylic acid as raw materials. The structure of the complex 1 was characterized by single crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy and thermogravimetry analysis. The zinc ions formed two secondary building units through protonated pyrazine-2,3,5,6-tetracarboxylic acid in complex 1. The building units interlace to form a two-dimensional layered structure, which further assembles into a three-dimensional supramolecular structure through weak hydrogen bond interactions. Fluorescence studies reveal that complex 1 exhibits competitive absorption toward Fe3+ resulting in significant fluorescence quenching and a low detection limit for Fe3+.
