This project will continue work on the development of methods for the chemical synthesis of single-chirality, structurally uniform carbon nanotubes. Despite intense scrutiny by scientists and engineers worldwide for nearly two decades, carbon nanotubes are still being made today by poorly understood, empirical, high temperature methods based on the transition metal-mediated capture of atomic, diatomic, and polyatomic carbon species from the gas phase. It is the goal of this project to develop synthetic organic chemical methods that will make possible the rational chemical synthesis of all-carbon single walled nanotubes that are closed at one end and open at the other, with predefined, uniform diameter, chirality, end cap structure, and rim structure. The project builds on and extends methods previously developed in the laboratory of the P.I. for the chemical synthesis of numerous geodesic polyarenes, including fullerene-C60. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Lawrence T. Scott of the Department of Chemistry at Boston College. Professor Scott's research efforts revolve around the development of methods for the synthesis of nonplanar networks of trigonal carbon atoms. Such chemistry could provide access to ultra thin, super strong, and light weight nanowires with metal-like electrical conducting properties. Successful development of the methodology will create new opportunities for advances in nanotechnology, from materials science and bioengineering to molecular scale circuitry and electronic devices.

该项目将继续致力于开发化学合成单手性、结构均匀的碳纳米管的方法。尽管近二十年来世界各地的科学家和工程师进行了严格的审查，但碳纳米管的制造仍然是基于过渡金属介导的原子、双原子和多原子碳气相捕获的高温方法。该项目的目标是开发有机合成化学方法，使一端封闭另一端开放的全碳单壁纳米管的合理化学合成成为可能，这些纳米管具有预定义的均匀直径、手性、端帽结构和边缘结构。该项目建立并扩展了先前在P.I.实验室开发的用于化学合成许多测地线聚芳烃的方法，包括富勒烯- c60。有了这个奖项，有机和大分子化学项目支持了波士顿学院化学系的劳伦斯·t·斯科特教授的研究。斯科特教授的研究工作围绕着三角碳原子非平面网络合成方法的发展。这种化学方法可以制造出超薄、超强、重量轻、具有类似金属导电特性的纳米线。该方法的成功开发将为纳米技术的进步创造新的机会，从材料科学和生物工程到分子尺度电路和电子设备。
