The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose was studied. A clear evidence of structure–activity relationship was found. The inorganic part of the hybrid ensured the availability of active sites for the reaction, while the organic cation part organized the structure and controled the diffusion of the reactants. This study can be used as a first approach to predict the symmetry, long range order and availability of active sites in the presented class of imidazolium based polyoxometalate hybrids.

葡萄糖在离子液体/磷钼酸盐杂化物上的差向异构：结构-活性关系

研究了一些离子液体/磷钼酸盐杂化物的晶体结构和化学性质对其在葡萄糖差向异构化中催化活性的影响。发现了结构-活性关系的明确证据。杂化物的无机部分确保了反应活性位点的可用性，而有机阳离子部分则组织了结构并控制了反应物的扩散。这项研究可以作为预测咪唑鎓类多金属氧酸盐杂化物提出的类别中活性位点的对称性，远距离有序性和可用性的第一种方法。
