摘　　要：以N,N′-双(4-吡啶甲酰胺)-3,4-噻吩(4-bpft)和对苯二甲酸(1,4-H_(2)bdc)为配体,在水热条件下合成了一种新的多孔配位聚合物Zn(4-bpft)(1,4-bdc)](CP 1).采用单晶X射线衍射、傅里叶变换红外光谱和粉末X射线衍射技术对其结构和组成进行了表征.结果表明,CP 1展示出二维网络结构,具有17.3%的溶剂可及空隙,呈现{6^(3)}拓扑的3-连接网络.CP 1具有明显的荧光开启性能,能有效检测天门冬氨酸(Asp);还表现出可逆的电化学氧化还原行为,可作为检测抗坏血酸(AA)的安培传感器.此外,CP 1能有效吸附有机染料亚甲基蓝(MB)、龙胆紫(GV)和中性红(NR),表明其在去除有机污染物方面具有潜在的应用价值.A porous coordination polymer Zn(4-bpft)(1,4-bdc)](CP1)was constructed from the N,N′-bis(4-pyridine formamide)-3,4-thiophene(4-bpft)and terephthalic acid(1,4-H_(2)bdc)mixed-ligand under hydrothermal condition.It’s structure and composition were characterized by means of single crystal X-ray diffraction,FTIR and PXRD techniques.The results show that CP1is a 2D network with 17.3%of solvent accessible void space by PLATON,which exhibits a 3-connected network with{6^(3)}topology.CP1displays obvious fluorescent turning on sensing and can efficiently detect asparticacid(Asp).It also exhibits electrochemically reversible redox behavior,and can be used as an amperometric sensor for detecting ascorbic acid(AA).In addition,the adsorption behavior of CP1was evaluated with organic dyes methylene blue(MB),gentian purple(GV),and neutral red(NR),implying it has potential application value in removing organic pollutants.
