In this work, a new type of zinc(II) coordination polymer {[Zn(HIDC)(BBM) 0.5 ]·H 2 O} n (Zn-CP) was synthesized using 4,5-imidazoledicarboxylic acid (H 3 IDC) and 2,2-(1,4-butanediyl)bis-1,3-benzimidazole (BBM) under hydrothermal conditions. Its structure has been characterized by infrared spectroscopy, elemental analysis and single crystal X-ray diffraction analysis. The Zn(II) ion is linked by the HIDC 2− ligand to form a zigzag chain by chelating and bridging, and then linked by BBM to form a layered network structure. Adjacent layers are further connected by hydrogen bond interaction to form a 3-D supramolecular framework. The solid-state fluorescence performance of Zn-CP shows that compared with free H 3 IDC ligand, its fluorescence intensity is significantly enhanced.

基于4,5-咪唑二羧酸盐和双（苯并咪唑）配体的2-D Zn（II）配位聚合物：合成，晶体结构和荧光性质

在这项工作中，使用4,5-咪唑二羧酸（H 3 IDC）合成了新型的锌（II）配位聚合物{[Zn（HIDC）（BBM）0.5]·H 2 O} n（Zn-CP）和在水热条件下的2,2-（1,4-丁二基）双-1,3-苯并咪唑（BBM）。其结构已经通过红外光谱，元素分析和单晶X射线衍射分析来表征。Zn（II）离子通过HIDC 2-配体连接，通过螯合和桥接形成锯齿形链，然后通过BBM连接形成分层的网络结构。相邻层通过氢键相互作用进一步连接以形成3-D超分子框架。Zn-CP的固态荧光性能表明，与游离的H 3 IDC配体相比，其荧光强度显着增强。
