This award supports research by Professor Alan Balch at the University of California at Davis concerned with the synthesis, structure, and characterization of assemblies of fullerenes into larger molecules. Procedures will be developed for the formation of nano-scale molecular materials that contain two or more fullerenes connected by a variety of transition metal complexes as bridging groups with donor groups (amine, phosphines) positioned close to the fullerene surface. These assemblies will be examined by X-ray crystallography, electrochemistry and their chemical reactivity will be determined, particularly with regard to cage coupling reactions. These studies will help to provide models for the types of metal binding sites that are present in the redox-active films resulting from the reduction of fullerenes in the presence of metal complexes such as Pd(acetate)2. The endohedral fullerene aspects of research involve an active collaboration with professor Harry Dorn at Virginia Tech. The broader impacts of this work involve the education of undergraduate, graduate, and postgraduate students in synthetic and structural supramolecular chemistry. As fullerenes and endohedral fullerenes are likely to be produced in bulk quantities, they are under active investigation for biomedical applications as MRI agents and as carriers of radiopharmaceuticals, as well as electronic applications.

该奖项支持加州大学戴维斯分校的Alan Balch教授的研究，该研究涉及富勒烯组装成更大分子的合成、结构和表征。将开发用于形成纳米级分子材料的程序，所述纳米级分子材料包含通过各种过渡金属络合物作为桥连基团与位于接近富勒烯表面的供体基团（胺、膦）连接的两个或更多个富勒烯。这些组件将通过X射线晶体学，电化学和它们的化学反应性进行检查，将被确定，特别是关于笼耦合反应。这些研究将有助于提供模型的类型的金属结合位点是存在于氧化还原活性膜中产生的还原富勒烯的金属络合物，如Pd（乙酸）2的存在下。内嵌富勒烯方面的研究涉及到与弗吉尼亚理工大学的哈里多恩教授的积极合作。这项工作的更广泛的影响涉及本科生，研究生和研究生的合成和结构超分子化学的教育。 由于富勒烯和内嵌富勒烯可能大量生产，因此它们作为MRI试剂和作为放射性药物的载体以及电子应用的生物医学应用正在积极研究中。
