title: Induction of gamma-turn-like structure in ferrocene bearing dipeptide chains via conformational control.
abstract: [structure: see text] A combination of the ferrocene scaffold as a central reverse-turn unit with the dipeptide chains (-L-Pro-L-Ala-NHPy) was demonstrated to induce both inverse gamma-turn-like and antiparallel beta-sheet-like structures. Only the antiparallel beta-sheet-like structure was formed in the ferrocene bearing the heterochiral dipeptide chains (-L-Pro-D-Ala-NHPy), in which highly organized self-assembly was achieved through a network of intermolecular hydrogen bonds.
