Peptide-based materials offer advantages for constructing supramolecular chiral systems due to their bioactivity and intrinsic chirality but precise control over the expression, transfer, and amplification of chirality is a significant challenge. Here, the authors demonstrate that achiral anions regulate hydrogen bonding interactions in dipeptide assembly, leading to the formation of chiral microrolls composed of 2D nanosheets.
