Fitting in : Hexagram‐shaped amphiphiles self‐assemble in the presence of a spherical, hydrophobic guest molecule to form a tetrahedron‐shaped tetrameric organic capsule in an aqueous methanol solution (see picture). In the presence of adamantane, an aqueous solution of a box‐shaped hexameric capsule composed of hexagram‐shaped amphiphiles was converted into a novel 1.7 nm sized tetrameric capsule that has an encapsulated adamantane template molecule.
