Abstract

Exohedrally functionalised fullerenes have been inserted in single-walled carbon nanotubes (SWNTs) with the aid of supercritical carbon dioxide to form peapods; C(61)(COOEt)(2) are encapsulated in SWNTs in high yield, whereas C(61)(COOH)(2) aggregate via hydrogen bonding to form a supramolecular complex, which sterically hinders encapsulation and causes it to adhere to the exterior surface of the SWNTs.

摘要

借助超临界二氧化碳，已将外表面官能化的富勒烯插入单壁碳纳米管（SWNTs）中以形成巴基管；C(61)(COOEt)(2) 以高产率被封装在单壁碳纳米管中，而C(61)(COOH)(2) 通过氢键聚集形成超分子复合物，这在空间上阻碍了封装并使其附着在单壁碳纳米管的外表面。
