Hierarchic self-assembly: The formation of a self-supporting elastic film without the use of macromolecular materials is described. The film is prepared by using a peptide-containing amphiphile that has three or four consecutive leucinate residues. The amphiphile initially forms β-sheet structures, which stack in a fastenerlike fashion between the side chains of leucine within the different β-sheets (see picture).
