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.
