Picking up the thread : The macrocycle bis‐ p ‐xylyl[26]crown‐6 is capable of forming pseudorotaxane‐like structures with single, nonconjugated urea or amide moieties when assisted by templating Na + ions (see example). By using this approach, rotaxanes were synthesized with glycine residues or the repeating unit of nylon‐6,6 as key components in the threadlike units.
