Solids and Polyanion Clusters with Oxovanadium and Oxomolybdenum Cores

该奖项授予无机化学、生物无机化学和金属有机化学项目，为雪城大学化学系Jon Zubieta博士对磷酸钒的研究提供持续支持。各种合成技术将被用来生产含有氧化钒和磷酸盐的新型结构。将使用水热方法来制备这些组分的大型多面体阵列，并将尝试将其他金属如钛、锆、锰、铁和钼加入到阵列中。不同排列的阵列将由钒砷酸盐和钒-有机砷酸盐制备。多官能团配体将被用来将簇连接成纳米级的结构。所有类型的阵列都将进行结构和磁性表征，并测试其结合有机阳离子的能力。本研究的长期目标是开发基于过渡金属/氧阴离子骨架的微孔材料的合理合成方法。合成这些材料所需的合成条件还不是很清楚，但已经制备了具有各种结构特征的分子阵列。由于这些化合物的热稳定性，它们是催化剂和催化剂载体的有吸引力的候选者，它们的各种结构形式可以产生不同的选择性和反应活性的催化剂。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program provides continued support for research on vanadium phosphates by Dr. Jon Zubieta of the Chemistry Department, Syracuse University. A variety of synthetic techniques will be used to produce novel structures containing vanadium oxide and phosphate. Hydrothermal methods will be used to produce large polyhedral arrays of these components, and attempts will be made to incorporate other metals such as Ti, Zr, Mn, Fe, and Mo into the arrays. Arrays with different arrangments will be prepared from vanadoarsenates and vanado-organoarsonates. Polyfunctional ligands will be used to connect clusters together into nanometer-scale structures. All types of arrays will be structurally and magnetically characterized, and tested for their ability to incorporate organic cations. The long-term goal of this research is to develop rational sythetic procedures for microporous materials based on transition metal/oxoanion frameworks. The synthetic conditions needed for sythesis of these materials are not well known, but molecular arrays with a great variety of structural features have been prepared. Because these compounds are thermally stable, they are attractive candidates for cataysts and catalyst supports, whose variety of structural forms could produce catalysts of various selectivities and reactivities.
