Solids and Polyanion Clusters with Oxovanadium and Oxomolybdenum Cores

该奖项在无机，生物无机和有机化学计划提供了对钒磷酸盐的研究由博士乔恩Zubieta的化学系，锡拉丘兹大学继续支持。 各种合成技术将用于生产含有钒氧化物和磷酸盐的新型结构。 水热法将用于生产这些组件的大型多面体阵列，并尝试将其他金属，如Ti，Zr，Mn，Fe和Mo纳入阵列。 将从钒砷酸盐和钒有机胂酸盐制备具有不同修饰的阵列。 多功能配体将用于将簇连接在一起形成纳米级结构。 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/含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并不为人所知，但已经制备了具有多种结构特征的分子阵列。 由于这些化合物是热稳定的，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各种选择性和反应性的催化剂。

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.
