| Outline of Final Research Achievements |
We constructed the complex between finite carbon nanotube, [4]cyclochrysenylene ([4]CC), and fullerene derivatives, and analyzed the interaction and rolling motion. We determined the association constant between [4]CC and C60 fullerene by using the fluorescence quenching titration to obtain the value which surpassed that of the previously tightest complex with C60. We succeeded to construct a molecular bearing by introducing "shaft" moiety to the fullerene and reveal its anisotropic rolling motion. We also investigated the relationship between the structures of fullerene derivatives and the binding affinities, and revealed that various fullerene derivatives including C70 and endhedral fullerenes could be applied as the journals for molecular bearings.
