We have analyzed the dynamical feature of a hexameric structure of nanocube (16) from a gear-shaped amphiphile molecule (1) upon addition of solvophobic spherical adamantane molecule (G), by means of molecular dynamics (MD) simulation, to elucidate the conversion mechanism from the hexameric nanocube G@16 to a tetrameric G@14 tetrahedron. The adamantane molecule (G) in the nanocube G@16 is located around the triple π stacking, although G in the G@14 tetrahedron is at the central position of the capsule. Our MD simulation shows that the nanocube G@16 is more fluctuated than the G@14 tetrahedron. We have also found that a demethylated nanocube G@26 is converted to a tetrameric G@23 tetrahedron due to the solvophobic effect for the adamantane molecule.
