Abstract
A tritopic receptor, in which three benzo[24]crown-8 macrorings are fused o nto a triphenylene core, forms very strong supramolecular bundle-like compl exes in CDCl3/CD3CN solution with trifurcated trications wherein three dibe nzylammonium ions are linked to a central benzenoid core. The triply thread ed superbundles, one of which has been characterized in the solid state by X-ray crystallography, dissociate completely via doubly and singly threaded intermediates when CD3SOCD3 is added progressively to the CDCl3/CD3CN solu tion.
