摘要：
A tritopic receptor, in which three benzo[24]crown-8 macrorings are fused onto a triphenylene core, forms very strong supramolecular bundle-like complexes in CDCl3/CD3CN solution with trifurcated trications wherein three dibenzylammonium ions are linked to a central benzenoid core. The triply threaded 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 solution.
