Professor Lawrence T. Scott, of the Department of Chemistry at Boston College, is supported by the Organic and Macromolecular Chemistry Program for his studies of the rational synthesis of fullerenes and other carbon-rich materials, including achiral, single-wall carbon nanotubes which are closed at one end and open at the other, with predefined uniform diameter, pitch, cap structure, and rim structure. As test cases for the methods and strategies employed, Professor Scott also explores the synthesis of low molecular weight (1500 amu) carbon-rich organic compounds with unusual structures, for which unusual molecular properties are anticipated.Fullerenes, carbon nanotubes, and related carbon-rich substances that are characterized by curved networks of carbon atoms have been widely acclaimed as materials of enormous potential value for future applications in materials science and the emerging field of nanotechnology. They also hold considerable intrinsic scientific interest owing to the unusual nature of their chemical structures. These fascinating substances are typically prepared by poorly-understood empirical methods, making control over which fullerenes or nanotubes are formed exceedingly difficult. With the support of the Organic and Macromolecular Chemistry Program, Professor Lawrence T. Scott, of the Department of Chemistry at Boston College, is developing rational synthetic routes to fullerenes and other "Buckymaterials," as well as to smaller carbon-rich organic molecules also anticipated to display unusual properties.

Lawrence T.斯科特，在波士顿学院化学系，是由有机和大分子化学计划的支持，他的研究富勒烯和其他富碳材料的合理合成，包括非手性，单壁碳纳米管是封闭的一端和开放的另一端，具有预定义的均匀直径，间距，帽结构和边缘结构。作为所采用的方法和策略的测试案例，Scott教授还探索了低分子量的合成。（1500 amu）具有不寻常结构的富碳有机化合物，预期其具有不寻常的分子性质。富勒烯，碳纳米管，相关碳-以碳原子弯曲网络为特征的丰富物质被广泛认为是未来具有巨大潜在价值的材料。在材料科学和新兴的纳米技术领域的应用。由于其化学结构的不寻常性质，它们也具有相当大的内在科学价值。这些令人着迷的物质通常是通过缺乏理解的经验方法制备的，这使得控制富勒烯或纳米管的形成非常困难。在有机和高分子化学项目的支持下，劳伦斯T。波士顿学院化学系的斯科特正在开发富勒烯和其他“巴克材料”的合理合成路线，以及更小的富含碳的有机分子，这些分子也有望显示出不同寻常的特性。
