Into the fold: Intramolecular CH⋅⋅⋅O hydrogen bonding has been utilized to create new aromatic triazole foldamers. Remarkably, all the triazole units of the foldamers are guided to orientate inward to form a nitrogen ring. As a result, they can efficiently bind neutral tri- and didentate organohalogens through multiple N⋅⋅⋅X (X=Cl, Br, I) halogen bonds to form stable 1:1 complexes.
