| Organic–inorganic hybrid polyoxometalates?POMs?have attracted increasing attention due to their diverse structural features and potential applications.POMs chemistry have developed toward to high nuclear and functionalization as the continuous progress of synthetic methods and detection methods.In this paper,the organic ligands and transition metal ions are selected to produce organic-inorganic hybrid compounds with simple structures and 1D,2D,and 3D structures.Nine novel inorganic-organic hybrid compounds have been successfully synthesized by adjusting the ratio of raw materials,temperature and the pH values under the method of conventional aqueous solution or hydrothermal synthesis.The organic-inorganic hybrids were fully characterized by a series of conventional analysis method,like IR spectroscopy,X-ray powder diffraction,Thermogravimetric analysis,et al.Meanwhile,the electrochemical property,Photodegradable dyes and magnetism of some compounds were studied.1.Three novel?-Keggin inorganic-organic hybrid compounds{[Zn?bpy?]3[Zn?bpy?2]Zn?OOCCH3?[PMo8VMo4VIO38?OH?2]}·2H2O?1?,?TBA?2{[Zn4?L?3]2[PMo8VMo4VIO38?OH?2]2}·2H2O?2?,?TBA?4[Zn4?L?][PMo8VMo 4VIO39?OH?]·4H2O?3?have been successfully synthesized by the hydrothermal method.Compounds 1-3 are insoluble in most common solvents and are very stable in solution.Electrochemical studies showed that compound 2 and3 show good electrocatalytic effects on the reduction of sodium nitrite and hydrogen peroxide.2.Three?-Keggin polyanion-based transition metal organic-inorganic compounds were obtained by hydrothermal synthesis method.H[Fe?2,2'-bipy?3]2[AlW12O40]·3H2O?4?,[Co2?H2O?2?4,4'-bipy??Hbipy?][AlW12O40]·H2O?5?,[Cu5?H2O?2?pz?6][AlW12O40]·2H2O?6?.We found that the different transition metal ions and ligands with different configurations would impact the structure of the product as synthesised.Photodegradation experiments show that compounds 5 and 6 exhibit good photocatalytic activity for RhB and MB.3.A?-[SiW12O40]5–polyanion-based transition metal organic-inorganic compounds[Cu4?pz?6][SiW12O40]·2H2O?7?were obtained by hydrothermal synthesis method.The2D network structure of the compound 7 is formed by the interconnection of pyrazine as a copper node.This compounds exhibits good photocatalytic activity for RhB and MB.4.A 3D organic-inorganic hybrid compound has been successfully synthesized by the conventional aqueous solution method.Magnetic measurements manifest that the complexes show antiferromagnetic behavior. |
