Functionalization Chemistry of Fullerenes

加州大学洛杉矶分校化学和生物化学系的伊夫·鲁宾教授在化学系的有机和高分子化学计划和材料研究部的固态化学计划的支持下，正在研究富勒烯的官能化化学。原子通过化学官能化方法结合到富勒烯中，使用合理的有机机制打破富勒烯衍生物中的键。原子或小分子插入生成的开放富勒烯之后是闭合反应，使富勒烯与其被捕获的物种再生。除了提供制备富勒烯的途径外，鲁宾教授的研究还提供了富勒烯化学反应的基本信息，导致了官能化富勒烯合成的进展，这些官能化富勒烯有望显示出有趣的材料性质，如电致发光和铁磁性。富勒烯具有独特的结构、拓扑和电子特征的组合。在发现和阐明富勒烯不寻常的物理和化学性质方面，特别重要的是发展了富勒烯的化学修饰和将原子和小分子结合到富勒烯壳层中的技术。在化学系的有机和高分子化学计划和材料研究部的固态化学计划的支持下，加州大学洛杉矶分校化学和生物化学系的伊夫·鲁宾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上产生和修复孔洞的选择性反应，鲁宾教授能够制备包含各种物种的富勒烯。这些研究为富勒烯的选择性化学修饰提供了新的方法，并为制备具有重要和有用的物理性能的材料提供了希望。

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.
