The syntheses of various two-and three-station mannosyl [c2] daisy chains, based on a dibenzo-24-crown-8 macrocyclic moiety and an ammonium, a triazolium, and a mono-or disubstituted pyridinium amide station, are reported. The ability of these molecules to act as molecular machine based mimetics has been further studied by 1H NMR studies. In all the protonated ammonium states, the interwoven rotaxane dimers adopt an extended co- ...
