“…The rotation of metallofullerenes between positions of fixed orientation is possibly influenced by the fluctuations in the strength of the dipole moment, caused by excitation. Electron beam irradiation might even provide an addressable means to drive rotations and translations of metallofullerenes in peapods for bucky-shuttle memory devices. – The atomic mass of La (138.90 g·mol −1 ) is larger than that of Sc (44.96 g·mol −1 ) and hence may require a greater angular impulse to change the orientation of a fullerene containing it.…”

We filled SWNTs with the paramagnetic fullerene Sc@C82 to form peapods. The interfullerene 1D packing distance measured using TEM is d = 1.1 +/- 0.02 nm. The Sc@C82 in SWNT peapods continuously rotated during the 2 s TEM exposure time, and we did not see the Sc atoms. However, Sc@C82 metallofullerenes in MWNT peapods have periods of fixed orientation, indicated by the brief observation of Sc atoms. La@C82 peapods were also prepared and their rotational behavior examined. The interfullerene 1D packing of both La@C82 and Sc@C82 peapods is identical and thus independent of the charge transfer state for these paramagnetic fullerenes. The La@C82 metallofullerenes in the peapods have fixed orientations for extended periods of time, up to 50 s in some cases. The La@C82 spontaneously rotates rapidly between fixed orientations.
