摘　　要：采用溶剂热法,以2,2'-联吡啶(bipy)为主配体,4,4'-二苯乙烯二羧酸(H2SDA)为辅助配体合成了一个链状配位聚合物[Zn(SDA)(bipy)]n·2H2O。通过红外吸收光谱(IR)、元素分析和X-射线单晶衍射等方法对配合物的结构进行表征。配合物属于单斜晶系,空间群P21/c,是由羧酸桥联形成的一维链状配位聚合物。对配合物的Hirshfeld表面及2D指纹图进行分析,在配合物的相互作用力中,H…H作用力占有率为43.3%,占主导作用,而C…H/H…C的作用力占有率为21.5%,O…H/H…O的作用力占有率为18.3%。配合物的荧光传感性能研究表明不同金属离子对配合物荧光强度有不同程度的影响,该配合物可作为荧光传感材料选择性检测Cu2+。The one-dimensional chain zinc complex[Zn(SDA)(bipy)]n·2H2O was synthesized by solvothermal method using 2,2'-bipyridine as the main ligand and 4,4'-stilbenedicarboxylic acid as the auxiliary ligand.The zinc complex was characterized by IR,elemental analysis and X-ray single crystal diffraction.The complex belong to the monoclinic system,space group P21/c,and formed one-dimensional chain coordination polymer by carboxylic acid bridging.Hirshfeld surface analysis and 2D fingerprint plots revealed that complex was supported mainly by H…H,the market share was 43.3%.The C…H/H…C and O…H/H…O interactions have 21.5%,18.3%contribution to the total Hirshfeld surface,respectively.The fluorescence sensing ability of the complex was investigated.The results show that the effects of different metal ions on the fluorescence of the complex was different,and it can be used as a fluorescence sensing material to detect Cu2+.
