Fullerene Based Supermolecular Assemblies

该奖项支持加州大学戴维斯分校艾伦·鲍尔奇教授关于富勒烯组装成更大分子的合成、结构和表征方面的研究。将开发程序来形成含有两个或两个以上富勒烯的纳米级分子材料，这些富勒烯由各种过渡金属络合物作为桥梁基团与靠近富勒烯表面的给体基团(胺、膦)相连。这些组装体将通过X射线结晶学和电化学反应进行检查，并将确定它们的化学反应活性，特别是关于笼形偶联反应。这些研究将有助于为氧化还原活性薄膜中存在的金属结合位点类型提供模型，该模型是在Pd(乙酸酯)2等金属络合物的存在下富勒烯还原产生的。研究的面内富勒烯方面涉及到与弗吉尼亚理工大学哈里·多恩教授的积极合作。这项工作的更广泛的影响涉及到本科生、研究生和研究生在合成和结构超分子化学方面的教育。由于富勒烯和面体内富勒烯可能大量生产，它们作为核磁共振试剂和放射性药物载体的生物医学应用正在积极研究中，以及电子应用。

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.
