This RUI award in the Inorganic, Bioinorganic, and Organometallic Chemistry program supports the work of Professor Greg Grant at the University of Tennessee at Chattanooga. The research focuses on a systematic investigation of the preparation of two- and three-dimensional metallosupramolecular complexes formed by transition metal mediated self-assembly. The project is specifically interested in using vertices based upon transition metal complexes with thiacrown ligands as subunits to direct the self-assembly of the supramolecular structure. The project is preparing two-dimensional structures such as squares and hexagons as well as proceeding to cubic three-dimensional structures. In particular, most platinum group metal complexes with these ligands show a rich electrochemical activity which can then be built into the polygons and polyhedra. Multiple oxidation states for the metal ions of the molecular square or cube can be accessed, enabling the overall charge of the square or cube to be fine-tuned. Controlling the overall charge of the self-assembled material has important consequences for its utilization in storage applications. The project has an ideal role in the education and training of young chemists to be future professionals. A two-year postdoctoral position modeled after the Dreyfus Foundation's Scholar/Fellow Program for Undergraduate Institutions is included. The postdoctoral Fellow is involved not only in the research project, but also in part-time teaching and research activities involving the undergraduate students. Nine undergraduate researchers including two at other undergraduate institutions, Covenant College and the College of St. Catherine, will be involved in the project. The PI, the postdoctoral Fellow, and the undergraduate students supported by the NSF RUI Grant are all members of a research team engaged in the study of these metallosupramolecular complexes. Self-assembled structures such as these are important in applications such as artificial molecular machines, strategic gas storage, heterogeneous catalysis, and an array of host-guest interactions. The ability of two-dimensional and three-dimensional metal organic networks, which can form porous, yet crystalline solids, has been exploited in fields such as hydrogen and methane storage.

这个RUI奖在无机，生物无机和有机化学计划支持教授格雷格格兰特在田纳西大学查塔努加的工作。 本论文系统地研究了过渡金属介导自组装制备二维和三维金属超分子配合物的方法。 该项目特别感兴趣的是使用基于过渡金属配合物的顶点与thiacrown配体作为亚基来指导超分子结构的自组装。该项目正在准备二维结构，如正方形和六边形，以及进行立方体三维结构。特别地，具有这些配体的大多数铂族金属络合物显示出丰富的电化学活性，其然后可以构建到多边形和多面体中。 可以获得分子正方形或立方体的金属离子的多种氧化态，从而能够微调正方形或立方体的总电荷。 控制自组装材料的总电荷对其在存储应用中的利用具有重要的影响。该项目对青年化学家的教育和培养具有理想的作用。一个为期两年的博士后职位仿照德雷福斯基金会的学者/研究员计划本科院校包括在内。 博士后研究员不仅参与研究项目，还参与涉及本科生的兼职教学和研究活动。 九名本科生研究人员，包括两名在其他本科院校，圣约学院和圣凯瑟琳学院，将参与该项目。PI，博士后研究员和NSF RUI资助的本科生都是从事这些金属超分子配合物研究的研究团队的成员。诸如此类的自组装结构在诸如人工分子机器、战略气体储存、多相催化和一系列主客体相互作用等应用中是重要的。 二维和三维金属有机网络的能力，可以形成多孔的，但结晶固体，已被开发的领域，如氢和甲烷的存储。
