Molecular motion of endohedral fullerenes in single-walled carbon nanotubes

Abstract:

Rock and roll: Endohedral fullerenes Ce@C82 inserted in single-walled carbon nanotubes (SWNTs) interact by electrostatic interactions and exhibit unusual dynamic behavior. Translational oscillations and discontinuous molecular rotations are observed (by high-resolution transmission electron microscopy) for the first time for molecular arrays inside SWNTs (see picture; blue dot=endohedral Ce atom). The fullerene rotation rate is different for isolated and aggregated nanotubes.

Selective host-guest interaction of single-walled carbon nanotubes with functionalised fullerenes.

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.
