The focus of this research is preparation of a series of polycyclic alkyne-bridged organometallic compounds. The target molecules represent hybrids of organometallic fullerenyne segments and the organic graphydiyne. They are of high interest as electro-active and extremely porous organometallic materials. The pyrolysis pyrolysis of large, alkyne-bridged cobalt- or iron-containing, highly unsaturated organometallics should lead to the formation of novel metal-carbon solids. The high-temperature pyrolysis of the proposed carbon-rich organometallics could lead to the formation of nanotubes, circumventing the use of gas phase conditions. The educational portion of the project will include curriculum development with a strong emphasis on the use of the Web.With this CAREER award, the Organic and Macromolecular Chemistry Program is supporting the research and educational activities of Dr. Uwe H. Bunz of the Department of Chemistry and Biochemistry at the University of South Carolina. Professor Bunz will focus his research on the preparation of organometallic compounds with the goal of constructing fullerenyne-segments and new metal-containing materials. Pyrolysis of the materials could serve as a method for the preparation of nanotubes. Carbon-rich compounds of the types proposed are of great interest as a new generation of advanced materials for future applications in electronic and photonic devices. The educational portion of the project will stress use of the Web in course development.

本研究的重点是制备一系列多环烷基桥接的有机金属化合物。靶分子为有机金属富勒烯段和有机石墨炔的杂化产物。它们作为电活性和极多孔的有机金属材料具有很高的兴趣。大的，炔桥式含钴或含铁的，高度不饱和的有机金属的热解应导致新的金属-碳固体的形成。所提出的富碳有机金属的高温热解可以导致纳米管的形成，绕过了气相条件的使用。项目的教育部分将包括课程开发，重点是网络的使用。有了这个职业奖，有机和大分子化学项目支持南卡罗来纳大学化学和生物化学系的Uwe H. Bunz博士的研究和教育活动。Bunz教授将专注于有机金属化合物的制备，目标是构建富勒烯段和新的含金属材料。材料的热解可以作为制备纳米管的一种方法。所提出的富碳化合物是未来电子和光子器件中应用的新一代先进材料。项目的教育部分将强调在课程开发中使用Web。
