Threading of di-, tri-, and tetra(ethylene glycol) through the macrocycle BPX26C6 in the presence of templating Na+ ions was proven by the synthesis of the corresponding [2]rotaxanes under solvent-free conditions. Among them, a [2]rotaxane featuring both tetra(ethylene glycol) and carbamate stations behaves as a molecular switch that can be controlled reversibly through the application of the KTFPB/[2.2.2]cryptand reagent pair.

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. Copyright
