Professor Yves Rubin, of the Department of Chemistry and Biochemistry at the University of California, Los Angeles, is studying the functionalization chemistry of fullerenes with the support of the Organic and Macromolecular Chemistry Program in the Division of Chemistry and of the Solid-State Chemistry Program in the Division of Materials Research. Atoms are incorporated inside fullerenes through a chemical functionalization approach using rational organic mechanisms for breaking bonds within fullerene derivatives. Insertion of atoms or small molecules inside the resultant open fullerenes is followed by closure reactions, regenerating the fullerenes with their entrapped species. In addition to providing preparative access to endohedral fullerenes, Professor Rubin's studies are providing fundamental information about the chemical reactivity of fullerenes, leading to advances in the synthesis of functionalized fullerenes expected to display interesting materials properties, such as electroluminescence and ferromagnetism.Fullerenes possess a unique combination of structural, topological, and electronic features. Of particular significance in the discovery and elucidation of the unusual physical and chemical properties of the fullerenes has been the development of techniques for their chemical modification and for the incorporation of atoms and small molecules within the fullerene shell. With the support of the Organic and Macromolecular Chemistry Program in the Division of Chemistry and the Solid-State Chemistry Program in the Division of Materials Research, Professor Yves Rubin, of the Department of Chemistry and Biochemistry at the University of California, Los Angeles, is developing new chemical methods to achieve these modifications. By the discovery of selective reactions capable of creating and of repairing holes in the fullerenes, Professor Rubin is able to prepare fullerenes containing a variety of species. These studies provide new methodologies for the selective chemical modification of the fullerenes and offer promise for the preparation of materials displaying important and useful physical properties.

洛杉矶的加州大学化学和生物化学系的Yves Rubin教授正在化学系的有机和高分子化学计划以及材料研究系的固态化学计划的支持下研究富勒烯的功能化化学。原子通过化学官能化方法并入富勒烯内，该方法使用合理的有机机制来破坏富勒烯衍生物内的键。原子或小分子插入到所得到的开放富勒烯中之后是闭合反应，使富勒烯与它们的捕获物质再生。Rubin教授的研究除了提供了对内嵌富勒烯的制备方法外，还提供了有关富勒烯化学反应性的基本信息，从而在功能化富勒烯的合成方面取得了进展，这些功能化富勒烯有望显示出有趣的材料特性，如电致发光和铁磁性。富勒烯具有独特的结构，拓扑和电子特征。在发现和阐明富勒烯不寻常的物理和化学性质方面，特别重要的是开发了化学修饰技术和在富勒烯壳内掺入原子和小分子的技术。在化学系的有机和高分子化学项目和材料研究系的固态化学项目的支持下，加州大学洛杉矶分校化学和生物化学系的Yves Rubin教授正在开发新的化学方法来实现这些修饰。通过发现能够在富勒烯中产生和修复空穴的选择性反应，鲁宾教授能够制备含有各种物质的富勒烯。这些研究为富勒烯的选择性化学修饰提供了新的方法，并为制备具有重要且有用的物理性质的材料提供了希望。
