Oxometal Complexes and Redox Catalysis

该奖项在无机，生物无机和有机化学计划支持研究教授克雷格L。希尔在埃默里大学阐明了一类新发现的钴和贵金属元素（主要是金和银）的末端金属氧配合物的结构、电子和其他物理性质，并研究了这些配合物活化分子氧和催化空气氧化的能力。 第二个目标是制备强大的手性微孔固体形成的对映体纯聚氧乙烯醚与连接阳离子的自组装和研究烯烃和其他有机底物的不对称氧化这些材料催化。 第三个目标是开发将大的多金属聚氧乙烯酸盐连接成巨大的晶体纳米结构的方法，并研究最近记录的这些巨大的簇和结构以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发展绿色化学催化系统，用于选择性的、原子经济的、与水相容的空气基有机氧化。 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，包括通过内部合作学者计划与海外几位顶级研究人员合作，并导致对妇女和代表性不足的群体进行科学研究的培训。

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.
