Description
Summary: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.
