| 摘要: 以5-氨基烟酸(5-anaH)为配体，采用水热法合成了1个锌(Ⅱ)的二维配位聚合物[Zn(5-ana)2]n(1)。通过元素分析、红外光谱、热重(TGA)和X-射线粉末衍射(PXRD)等手段对其进行了表征，并用X-射线单晶衍射法测定了配位聚合物的单晶结构。该配位聚合物属于正交晶系，P212121空间群，为2D层状结构。我们在室温下对其二次谐波产生效率及荧光性质进行了研究，结果表明，该配位聚合物具有二级非线性光学效应，可作为潜在的二阶非线性光学材料，配位聚合物荧光相对于配体5-氨基烟酸发生了蓝移。 |

| Abstract: A 2Dcoordination polymer [Zn(5-ana)2]n(1), based on a rigid ligand 5-ana(5-anaH=5-aminonicotinic acid)has been synthesized by hydrothermal method and characterized by elemental analysis, IR spectra, TGA, XRD, and the crystal structure was determined by single-crystal X-ray diffraction. The coordination polymer crystallizes in the orthorhombic system, space group P212121, and features 2D layer structure. Second harmonic generation efficiency and fluorescence of the coordination polymer are also further investigated. The results show that this coordination polymer has a second harmonic generation, which can be used as a second-order nonlinear optical material. Fluorescence of the coordination polymer exhibits a blue shift compared with free ligand. |
