A simple motif for molecular recognition—the binding of disubstituted ammonium salts, for
example dibenzyl‐and di‐n‐butylammonium hexaflurophosphate, with crown ethers like …

Two novel [2] rotaxanes, comprised of a dibenzo [24] crown-8 (DB24C8) macroring bound
mechanically to a chemical “dumbbell” possessing two different recognition sites viz …

A template‐controlled, one‐pot reaction afforded the [2] catenane 1 in 70% yield. Compound
