With this new award, the Organic and Macromolecular Chemistry Program supports the work of Professor Yves F. Rubin, of the Chemistry Department at the University of California-Los Angeles. This research will involve investigations of the synthesis and properties of fullerenes with substitutents both inside and outside of the cage. The synthesis of endohedrally substituted will follow a designed chemical functionalization approach ("molecular surgery") for breaking bonds within fullerene derivatives. Insertion of atoms or small molecules inside these open fullerenes will be followed by reclosure reactions to regenerate the integral fullerenes with their entrapped species. The ultimate goal of these experiments is the large scale preparation of endohedral metallofullerenes. Additional studies directed at regioselective functionalization on the outside of the fullerene cage will be carried out. In these investigations, multiple natural or unnatural amino acid units will be attached to the fullerene framework to build medium-sized peptide chains on fullerene scaffolds. Graduate students, undergraduates, and postdoctorals engaged in this research will receive highly multidisciplinary training in sophisticated organic synthesis, crystal growth, X-ray diffraction, ESR spectroscopy, and magnetometry. These experiments are expected to aid in the development of advanced materials with nonlinear optical, magnetic, and superconducting properties.

有了这个新的奖项，有机和高分子化学计划支持教授伊夫F。加州大学洛杉矶分校化学系的鲁宾说。 本研究将探讨笼内外取代富勒烯的合成与性质。 内面取代的合成将遵循设计的化学官能化方法（“分子手术”），用于破坏富勒烯衍生物内的键。在这些开放的富勒烯内插入原子或小分子之后，将进行再封闭反应，以再生具有其捕获物质的完整富勒烯。这些实验的最终目标是大规模制备内嵌金属富勒烯。 将进行针对富勒烯笼外部区域选择性官能化的其他研究。 在这些研究中，将多个天然或非天然氨基酸单元连接到富勒烯框架上，以在富勒烯支架上构建中等大小的肽链。 从事这项研究的研究生，本科生和博士后将接受复杂的有机合成，晶体生长，X射线衍射，ESR光谱学和磁力学的高度多学科培训。 这些实验有望帮助开发具有非线性光学、磁性和超导特性的先进材料。
