摘要
采用水热法合成了一个新的一维铅(Ⅱ)配位聚合物[Pb(QOA)2]n(QOA=8-喹啉氧基乙酸根离子),通过红外光谱、元素分析和X-射线单晶衍射分析给予表征。该配位聚合物属于单斜晶系,C2/c空间群。晶胞参数a=2.113 2(2)nm,b=1.189 86(7)nm,c=0.790 73(2)nm,β=99.081(3)°,V=1.963 3(4)nm3,Z=4。固体UV-Vis-NIR漫反射光谱结果显示它的光学能隙约为3.4 eV,表明配合物具有潜在的半导体性质。固体荧光测定表明配合物表现出良好的荧光性质。
The new one-dimensional Pb(Ⅱ) coordination polymer [Pb(QOA)2]n (QOA=8-quinolinyloxyacetate anion) was synthesized by hydrothermal method,and its structure is characterized by IR,elemental analysis and single crystal X-ray diffraction analysis.The crystal belongs to monoclinic system and space group C2/c with unit cell parameters a=2.113 2(2) nm,b=1.189 86(7) nm,c=0.790 73(2) nm,β=99.081(3)°,V=1.963 3(4) nm3,Z=4.Solid UV-Vis-NIR diffuse reflectance spectra results suggest the complex has the potential semiconductor property.The solid fluorescence spectra results exhibit the complex has good fluorescence property.CCDC:939269.
