In this project, development of the chemical functionalization of carbon nanotubes and control of its property were studied. Reductive alkylation of single-walled carbon nanotubes (SWNTs) was conducted and its results showed significant substituent effects on the degree of functionalization of SWNTs. Addition of reactive substituent was successfully achieved using protectional group. Preparation and analysis of di-alkylated SWNTs having various substituents through two-step reductive alkylation were conducted. The degree of the functionalization on SWNTs (Bu-SWNTs-Bu) were determined by the absorption and Raman spectroscopy and the thermogravimetric analysis (TGA) and there is a good relation between Raman spectra and TGA. On the basis of the relation between Raman spectra and TGA, the ratio of 2R to 1R of 1R-SWNTs-2R (formula mass: 1R ≠ 2R) was determined. We also developed the chiral-selective photoreaction of SWNTs with organosulfur compounds in the presence of oxygen.

本项目主要研究碳纳米管的化学功能化及其性能控制。对单壁碳纳米管（SWNTs）进行了还原烷基化反应，结果表明取代基对SWNTs的功能化程度有显著影响。使用保护基成功地实现了反应性取代基的加成。采用两步还原烷基化法制备了具有不同取代基的双烷基单壁碳纳米管。通过吸收光谱、拉曼光谱和热重分析（TGA）对单壁碳纳米管（Bu-SWNTs-Bu）的功能化程度进行了表征，发现拉曼光谱和热重分析之间有很好的相关性。根据拉曼光谱与热重分析的关系，确定了1 R-SWNTs-2 R（分子量：1 R <$2R）的2 R与1 R的比例。我们还开发了单壁碳纳米管与有机硫化合物在氧气存在下的手性选择性光反应。
