摘要
通过水热条件合成了2种基于多酸的超分子化合物(H_2L)_2SiW_(12)O_(40)(1)和(HL(H_2L)(PMo_(12)O_(40))(2)(L=1,3-二(咪唑基)丙烷),使用元素分析、X-射线粉末衍射、X-射线单晶衍射、以及热重分析等对化合物进行了表征.单晶衍射分析表明化合物1和2属于三斜晶系,空间群为Pī.在这2个化合物中,质子化的配体作为阳离子来平衡整个分子的电荷.多酸和配体通过氢键链接形成三维结构.荧光和电化学性质研究表明,化合物1的荧光主要来自配体贡献.电化学分析为以后制备电化学传感器提供了理论基础.
Two supramolecular compounds(H2L)2SiW12O40(1),(HL(H2L)(PMo12O40)(2)(L=1,3-2(imidazole)propane)were synthesized by hydrothermal conditions,and the compounds have been characterized by elemental analysis,X-ray powder diffraction(XRD),X-ray single crystal diffraction,and thermogravimetric analysis.Single crystal diffraction analysis showed that compounds 1 and 2 belong to triclinic crystal system,space group Pī.In these two compounds,the ligands were protonated to balance the charge of the molecules.POMs and ligands are formed through hydrogen bonds to become 3 Dstructures.And the fluorescence and electrochemical properties of compound 1 were tested.Fluorescence showed that fluorescence mainly from ligand contribution.Electrochemical analysis provide a theoretical basis for the preparation of electrochemical sensor.
