摘要:无机-有机杂化多酸化合物具有优良的物理、化学性质,对其开展深入研究具有重要的意义。通过水热合成方法合成了化合物[H_2pca][H_3SiW_(12)O_(40)]·2H_2O(1)(pca=吡啶-4-甲酸),并对其结构和性质进行研究。经X线单晶衍射仪检测并分析发现,该化合物属于单斜晶系、C2/m空间群,通过配体与多酸之间的氢键形成三维的超分子结构。通过红外光谱、X线粉末衍射、荧光光谱、热重分析对其性质进行表征,在进行荧光光谱分析时发现,该化合物在λ=410 nm处存在荧光吸收峰,并具有较好的热稳定性。该研究可丰富无机-有机杂化多酸化合物的家族,为进一步应用研究打下基础。
Polyoxometalate (POM) -supported inorganic - organic hybrid compounds have attracted extensive attention for its su- perior physical and chemical properties. It is important to research. [ H2pca ] [ H3 SiW12O40 ] 2H2O ( 1 ) ( pca = Pyridine - 4 - car- boxylic acid), which has been obtained by hydrothermal methods and characterized by single -crystal X -ray diffraction analyses, IR spectra, powder X - ray diffraction, and thermal analyses. It belongs to monoclinic crystal system and C2/m space group. Hydrogen bonds of ligand and [ SiW12O40 ]4- lead to a three - dimensional supramolecular structure. In addition, fluorescence spectra was also in- vestigated. The experimental results show that the compound has a fluorescence absorption peak at λ = 410 nm, and also has good thermal stability. This work extends POM - supported inorganic - organic hybrid compounds, and it will be a strong foundation for fur- ther application.
