    • This invention provides improved methods for the derivatization and solubilization of fullerenes, which are particularly useful for those fullerenes that are normally insoluble and which are specifically applied, among others, to endohedral fullerenes, including endohedral metallofullerenes; empty fullerenes, including small-bandgap fullerenes and other insoluble fullerenes and to very high molecular weight fullerenic materials generated in fullerenic soot, including giant fullerenes, fullerenic polymers, carbon nanotubes and metal-carbon nanoencapsulates. More specifically the invention relates to improved methods for cyclopropanation of fullerenes. Specific reaction conditions are provided which allow for cyclopropanation reactions to be succesfully performed for the first time on insoluble classes of fullerenes. Also provided is a method for purification of one or more fullerenes from a fullerenic material containing the one or more fullerenes in addition to non-fullerenic carbonaceous material, particularly amorphous carbonaceous material, by derivatizing one or more fullerenes using the methods of the invention and separating soluble derivatizes fullerenes from insoluble materials.
    • 本发明提供了富勒烯的衍生和溶解的改进方法,其特别适用于那些通常不溶的富勒烯,特别适用于内含富勒烯(包括内嵌金属富勒烯)的富勒烯; 空的富勒烯,包括小带隙富勒烯和其他不溶性富勒烯,以及在富勒烯烟灰中产生的非常高分子量的富勒烯类材料,包括巨富勒烯,富勒烯聚合物,碳纳米管和金属碳纳米胶囊。 更具体地,本发明涉及用于富勒烯的环丙烷化的改进方法。 提供了具体的反应条件,其允许在不溶性类别的富勒烯上首次成功地进行环丙烷化反应。 还提供了一种通过使用本发明的方法衍生一种或多种富勒烯并将本发明的方法分离出来,从含有一种或多种富勒烯的富勒烯材料中除非富勒烯碳质材料,特别是无定形碳质材料之外纯化一种或多种富勒烯的方法 可溶性衍生自不饱和物质的富勒烯。
