Self-Assembled Interwoven Cages from Triptycene-Derived Bis-Macrotricyclic Polyether and Multiple Branched Paraquat-Derived Subunits

On the basis of formation of a 1:2 complex between the triptycene-derived bis-macrotricyclic polyether and the paraquat derivative, two novel well-defined interwoven supramolecular cages were constructed by the [3 + 2] and [4 + 2] self-assembly of the polyether and trifurcated and cross paraquat-derived subunits under millimolar concentrations, respectively.
