relevance for individualised patient management.In this study, a twisted macrocycle was synthesized via ring closure of a double-helical aromatic oligoamide foldamer with two disulfide bridges. Single-crystal X-ray structure and NMR spectroscopy demonstrate the twisted conformation of macrocycle both in the solid state and in solution. As a result of the rearrangement of hydrogen bonding preference, the twisted conformation could be transformed to boxlike through protonation of the pyridine segments of macrocycle. In addition,
