Electrospray mass spectrometry (ESMS) has been demonstrated to be a powerful technique for the characterisation - at both a molecular and a supramolecular level - of a series of highly-ordered catenanes based on interlocking rings composed of (i) macrocyclic polyethers containing either two π-electron rich 1,4-dioxybenzene or 1,5-dioxynaphthalene groups linked by 3,6,9-trioxaundecyl chains and (ii) tetracationic cyclophanes containing two π-electron deficient bipyridinium units linked by either p-xylyl or bitolyl residues.
