The reconstruction and control of supramolecular ropes using minimalist building units remains a fundamental challenge. Here the authors demonstrate self-assembly of cyclo-tryptophan-proline dipeptide stereoisomers into crystalline supramolecular triple-helical structures with tunable S- or Z- twists governed by the configuration of tryptophan residues.
