Helices and nanotubes on folding compositions and method of making same
Download pdf
Abstract/Description: | Helical oligomer and polymer compositions that form nanotubes are described. The compositions comprise a plurality of aromatic substituents linked by at least one amide group. The compositions have a curved backbone due to intramolecular hydrogen bonds that rigidify the amide linkage of each amide group to each aromatic substituent and due to an interaction between the aromatic substituents such that the curved backbone is stabilized. The helical compositions are formed by ridigifying the amide group, which is flanked on each side by the aromatic substituents, by introducing intramolecular hydrogen bonds into a linkage between the amide group and each aromatic substituent such that the compositions fold into a helical shape when the amide linkages are meta to each other. |
