wherein cyclobis(paraquat-p-phenylene) is interlocked with polyether macrocyclescontaining, in addition to one 3,5-bis(oxymethylene)-1H-1,2,4-triazole unit, either one 1,4-dioxybenzene or one 1,5-dioxynaphthalene ring system. We also report 2) the full characterization of both [2]catenanes by fastatombombardmentmassspectrometry (FABMS), X-ray crystallography, and dynamic (1)H NMR spectroscopy. We
