dialkylammonium recognition sites at the magic distance of 3.5 Å apart in the dumbbell components of a series of oligorotaxanes (see picture) renders otherwise conformationally floppy [n]rotaxanes rigid and rodlike. These oligorotaxanes form with near‐quantitative conversion under thermodynamic control using dynamic covalent chemistry.
