For the acheivement of a ubiquitous network, it is essential to store a large amount of information. If the recordable molecules or some nanoparticles are arranged in a well-organized manner, the density of the stored information in the limited area increases remarkably. Fullerene can act as a recordable molecule due to its excellent electrochemical and photochemical properties. In this paper, we have developed a procedure to prepare the ultra-thin film of supermolecules of a spherical fullerene and water-soluble hosts. Fullerene is so hydrophobic that it easily forms a three-dimensional aggregate on the water surface. When fullerene was spread on a host solution, the fullerene was captured by the host at the air-water interface and formed amphiphilic supermolecule. The morphology of the supramolecular assembled films was examined by changing the host molecules, the initial density of fullerene, the subphase temperature and the additives in the subphase.
