Surface modification of single wall carbon nanotubes(SWCNT) by addition of various nitrogen organic compounds were studied. Reaction of SWCNT with phenylhydrazine derivatives proceeded in the presence of a surfactant to give adducts. The products analyzed to contain one phenylhydrazine molecule per 125--300 carbon atoms were soluble in common organic solvents. The reaction efficiency was higher when electron donative substituent was located on phenylhydrazine. Thermal elimination of the hydrazine unit from the products occurred at 500℃ to give SWCNT in which the original bundling structure was resolved. Therefore, we have made it appear that the hydrazine addition reaction was new methods for homogeneous dispersion and fine molecular process of SWCNT. As the model substrate of SWCNT, we employed fullerene derivatives to investigate various addition reactions of organonitrogen compounds. In these reactions, synthesis of fullerene derivatives with large orifice was accomplished, and the products were suitable for incorporation of small molecules into inside space of fullerene. Finally, we have first succeeded to synthesize fullerne derivative incorporating water.

研究了通过添加各种氮有机化合物对单壁碳纳米管（SWCNT）进行表面改性，在表面活性剂存在下进行单壁碳纳米管与苯肼衍生物的反应，得到加合物，经分析，产物中每 125--300 个苯肼分子。当给电子取代基位于苯肼上时，碳原子可溶于普通有机溶剂，反应效率更高。在500℃下，产物中的肼单元发生分解，得到单壁碳纳米管，其中原始的成束结构被分解，因此，我们发现肼加成反应是单壁碳纳米管均匀分散和精细分子加工的新方法。我们以单壁碳纳米管模型为基础，利用富勒烯衍生物研究了有机氮化合物的各种加成反应，在这些反应中，完成了大孔径富勒烯衍生物的合成，并得到了产物。适合将小分子掺入富勒烯内部空间，最终我们首次成功合成了掺入水的富勒烯衍生物。
