With this award, the Organic and Macromolecular Chemistry Program supports the work of Professor W. E. Billups, of the Chemistry Department at William Marsh Rice University. The research will extend the PI's investigations of strained reactive intermediates, single wall carbon nanotubes (SWNTs), and fullerenes. Highly strained organic molecules of current theoretical interest will be prepared. Since these compounds will be unstable at room temperature, their structure will be determined by low temperature x-ray crystallography. Although the extraordinary electronic and mechanical properties of SWNTs suggest important applications, progress has been limited due to the insolubility of these substances in organic solvents. In order to circumvent this problem an efficient and scalable route to solublized SWNTs will be developed. In addition, a series of fullerene investigations will be initiated. Included will be studies of highly reduced fullerenes as vehicles for storage of dihydrogen, the isolation of large fullerenes that are formed during the synthesis of carbon nanotubes, and investigations of fullerenes found in meteorites.In addition to providing fundamental information on the chemistry of energetic molecules and advanced materials, these studies will provide important interdisciplinary training for undergraduate and graduate students. The involvement of these students in international collaborations will be especially valuable.

有了这个奖项，有机和高分子化学计划支持教授W。E.威廉·马什·赖斯大学化学系的比卢普斯说。 这项研究将扩展PI对应变反应中间体，单壁碳纳米管（SWNTs）和富勒烯的研究。 将制备当前理论上感兴趣的高度应变的有机分子。 由于这些化合物在室温下不稳定，因此它们的结构将通过低温X射线晶体学来确定。 虽然单壁碳纳米管的特殊的电子和机械性能表明重要的应用，进展一直受到限制，由于这些物质在有机溶剂中的不溶性。 为了规避这个问题，将开发一种有效的和可扩展的途径来解决SWNT。 此外，还将启动一系列富勒烯研究。 其中包括高度还原的富勒烯作为储存氢的载体的研究，碳纳米管合成过程中形成的大富勒烯的分离，以及陨石中发现的富勒烯的研究。除了提供高能分子和先进材料的化学基础信息外，这些研究将为本科生和研究生提供重要的跨学科培训。 这些学生参与国际合作将特别有价值。
