在水热法条件下,4-羟基间苯二甲酸(H2HPHA)和锌离子分别与1,2二(吡啶4-基)乙烯(dpee)及4,4'-联吡啶(4,4'-bpy)反应得到了2个三维的配位聚合物[Zn(HPHA)(dpee)·(DMA)2]n(配合物1)和[Zn(HPHA)2(4,4'-bpy)2·DMA]n(配合物2).用X射线单晶衍射测定了配合物的晶体结构,结果显示:配合物1属于单斜晶系,C2空间群,每个不对称单元由一个锌离子,一个4-羟基间苯二甲酸配体及一个1,2-二(吡啶-4-基)乙烯组成;配合物2属于单斜晶系,P12/c1空间群,每个不对称单元由两个锌离子,两个4-羟基间苯二甲酸配体及两个4,4'-联吡啶配体组成.荧光光谱分析结果表明:配合物1的最强激发峰和发射峰在分别在25 1和397 nm,配合物2的最强激发峰和发射峰分别在415和513 nm.热重分析表明两个配合物在室温下稳定.
Synthesis,Crystal Structures and Fluorescent Properties of Zn(Ⅱ)Complexes Based on 4-Hydroxyisophthalic Acid and Nitrogen-Containing Heterocyclic Ligands
Under hydrothermal method condition,4-hydroxyisophthalic acid(H2HPHA)and Zn(Ⅱ)ions reacted with 1,2-di(pyridin-4-yl)ethene(dpee)and 4,4-bipyridine(4,4'-bpy)to obtain two coordination polymers[[Zn(HPHA)(dpee)·(DMA)2]n(complex 1)and[Zn(HPHA)2(4,4'-bpy)2·DMA]n(complex 2).The crystal structures were determined by single crystal X-ray diffraction method.The results show that complex 1 crystallizes in the monoclinic space group C2 with each asymmetric unit consisting of one Zn(Ⅱ)ion,one 4-hydroxyisophthalic acid ligand and one 1,2-di(pyridin-4-yl)ethene ligand.Complex 2 crystallizes in the monoclinic space group P12/c1 with each asymmetric unit consisting of two Zn(Ⅱ)ions,two 4-hydroxyisophthalic acid ligands and two 4,4'-bipyridine ligands.Fluorescence spectrum analysis show that the excitation peak of complex 1 is 251 nm,emission peak is 397 nm.The complex 2 is 415 nm,emission peak is 513 nm.The thermal stability study shows that the complexes are stable at room temperature.
