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.

研究了不同含氮有机物对单壁碳纳米管（SWCNT）表面的改性。在表面活性剂的作用下，swcnts与苯基肼衍生物反应生成加合物。经分析，每125 ~ 300个碳原子中含有1个苯肼分子的产物可溶于普通有机溶剂。在苯基肼上放置电子取代基时，反应效率较高。在500℃的温度下，产物中的联氨单元发生热消除，从而得到原有的成束结构被分解的swcnts。因此，我们认为联氨加成反应是制备纳米碳纳米管均匀分散和精细分子化的新方法。作为swcnts的模型底物，我们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，产物适合于小分子掺入富勒烯的内部空间。最后，我们首次成功合成了含水的富勒烯衍生物。
