On the basis of molecular design and assembly, the polyoxometalate compounds supported by Keggin, Dawson, lacunary Keggin, and Silverton-type etc. polyanions on the basis of well-known and novel polyanions as building blocks were successfully synthesized by the hydrothermal technique, which are"decorated"or"bridged"by organic N-donor and/or O-donor ligands. The study on synthetic conditions and rules for these hybrid compounds and characterization by X-ray crystallography, spectroscopic, thermal, electrochemical and magnetic properties are carried out.

Hybrid mesoporous molecular sieve materials with hexagonal mesoporous structure and covalent bonded polyoxometalates were synthesized based on tetraethoxysilane anti lacunary polyoxometalate, SiW11, via sol-gel method in the presence of triblock copolymers P123 as the structure-directing agent. The influences of molar ratio of inorganic precursors and aging temperature on the structure and the loadings of SiW11 in the hybrid materials were investigated. Some reaction details in the synthesis were revealed.
