![]() Combining their single-crystal XRD structure and in silico results, it was demonstrated that the spatial orientations of aromatic moieties were subtly changed by heterochirality of peptide building blocks, which led to intramolecular face-to-face interactions. In contrast, heterochiral nanotubes formed by Ff and fF manifest superstructures along the axial direction with differed thermal and mechanical strength (Young’s modulus: 7.3 ± 2.4 GPa for Ff and 8.3 ± 2.1 GPa for fF). The homochiral peptide FF and its enantiomer ff formed nanotubes with high thermal and mechanical stabilities (Young’s modulus: 20.3 ± 5.9 GPa for FF and 21.2 ± 4.7 GPa for ff). Pronounced effects relating to heterochirality on mechanostability and thermal stability can be identified. A series of nanotube structures based on diphenylalanine (FF) and its chiral derivatives were examined. In this work, we illustrate a strategy for constructing heterochiral peptide architectures with distinct structural, mechanical and thermal characteristics.
