项目摘要

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Prof. Craig L. Hill at Emory University to elucidate the structural, electronic and other physical properties of a newly discovered class of terminal metaloxo complexes of the coinage- and noble-metal elements (primarily gold and silver) and to investigate the ability of these complexes to activate dioxygen and catalyze air-based oxidations. A second goal is to prepare robust chiral microporous solids formed by self assembly of enantiopure polyoxometalates with linking cations and to investigate asymmetric oxidations of alkenes and other organic substrates catalyzed by these materials. A third aim is to develop methods to link large multi-metal polyoxometalates into giant crystalline nanostructures and to investigate the recently documented ability of these giant clusters and structures to catalyze green oxidations with air as the oxidant and water as the solvent. The systems under study should further the development of green chemistry catalytic systems for selective, atomeconomic, air-based organic oxidations compatible with water. The research will facilitate development of cyber infrastructure, provide tutelage for young scholars through multi-institution interactions and collaborations, including those with several top researchers overseas, via an in-house collaborative scholars program, and lead to the training of women and underrepresented groups in scientific research.

该奖项在无机，生物有机和有机金属化学计划中支持埃默里大学的Craig L. Hill教授的研究，以阐明新发现的一类终端金属氧化物的结构，电子和其他物理特性元素（主要是黄金和银色），并研究这些复合物激活二氧化物并催化空气氧化的能力。第二个目标是准备通过与阳离子的映射多氧碱自组装形成的强大手性微孔固体，并研究这些材料催化的烯烃和其他有机底物的不对称氧化。第三个目的是开发方法，将大型多金属多氧元素连接到巨大的晶体纳米结构中，并研究这些巨大簇和结构最近记录的将用空气作为氧化剂和水作为溶剂催化绿色氧化的能力。所研究的系统应进一步开发绿色化学催化系统，以选择与水兼容的选择性，原子经济，基于空气的有机氧化。这项研究将促进网络基础设施的发展，通过多机构的互动和合作为年轻学者提供指导，包括在海外的几位顶级研究人员，通过内部合作学者计划，并导致对妇女和人为不足的团体的培训科学研究。
