Carbon nanahorns (CNH) were functionalized following the methodology of 1,3-dipolar cycloaddition of azomethine ylides and found to form stable solutions in either organic solvents or water. The number of added functional units, in the form of pyrrolidine moieties, was calculated when a pyrene chromophore was utilized in the modification scheme. Moreover, complementary theoretical calculations revealed that reactivity enhancement is expected at locations near the conical-shaped tip of CNH, where the highest curvature and strain exist. Finally, additional organic transformation of already modified CNH was exploited by covalently linked ferrocene units.
碳纳米角（CNH）按照甲亚胺叶立德的1,3-偶极环加成方法进行功能化处理，结果发现其在有机溶剂或水中均可形成稳定溶液。当在修饰方案中使用芘发色团时，计算了以吡咯烷部分形式存在的添加功能单元的数量。此外，补充理论计算表明，在碳纳米角锥形尖端附近曲率和应变最高的位置，反应活性预计会增强。最后，通过共价连接二茂铁单元对已修饰的碳纳米角进行了额外的有机转化。
