含双咪唑配体的锌配位聚合物的晶体结构、荧光性质及抑菌性能研究(英文)

Structural Characterization,Luminescence Behavior and Antimicrobial Study of a Zinc Coordination Polymer Based on Bis(imidazole) Ligand

本文报道了一个基于双咪唑配体的锌配位聚合物[Zn(oxa)(bbi)]n(1)(oxa=草酸,bbi=1,1′-(1,4-丁二基)双咪唑),并对该化合物进行元素分析、红外和X-射线单晶衍射分析。结果表明标题化合物通过配位键和π-π堆积作用力形成了一个由(4,4)拓扑形状的二维网络组成的具有大孔洞的三维金属有机框架结构。除此之外,测定了配合物1的荧光发射光谱并对其微生物抑菌性能进行了初步研究。

A coordination polymer based on zinc（Ⅱ） and mixed ligands [Zn（oxa）（bbi）]n（1）（oxa=oxalate anion,bbi=1,1′-（1,4-butanediyl）bis（imidazole））,has been prepared and characterized by single-crystal X-ray diffraction.The structure of polymer 1 presents an unique two-dimensional（2D） layer structure with（4,4） topology in the presence of meso-helical chains and a three-dimensional（3D） network distorted with large channels.In addition,moderate fluorescent emission in the solid state at room temperature was observed in the Zn1-containing polymeric compound 1.And antimicrobial activity of the compound has been investigated.CCDC： 842497.
