The objectives of this research are to synthesize new organic- inorganic layered structured with adsorption sites for specific organic molecules and to investigate the synthesis of new extended lattices based on connected frameworks of VO5 square pyramids with tetrahedral oxyanions. Subsequent removal of the guest species from the solid leads to compounds which can show highly selective molecular sorption and ion complexation in subsequent reactions. The new phases will be characterized by powder and single crystal diffraction methods, magnetic susceptibility measurements and the determination of sorption isotherms and kinetics. These studies are of special value in catalysis for processes involving the production of fuels and chemicals.

这项研究的目标是合成具有特定有机分子的吸附位点结构的新有机无机分层，并研究基于与四面体氧气的VO5方形金字塔的连接框架的新扩展晶格的合成。 随后将客人物种从固体导管中切除到化合物中，这些化合物可以在随后的反应中显示出高度选择性的分子吸附和离子络合。 新阶段将以粉末和单晶衍射方法，磁化率测量以及吸附等温度和动力学的测定来表征。 这些研究在涉及燃料和化学物质生产的过程的催化中具有特殊的价值。
