Triptycene-derived macrotricyclic polyether was proved to be an efficient "molecular glue" for cross-linking the copolymer containing dibenzylammonium salts to form supramolecular polymer networks via host-guest complexation, which was evidenced by H-1 NMR spectroscopy, solution viscometry, and formation of transparent and elastic supramolecular polymer gels. Interestingly, a well-defined porous structure of the supramolecular polymer gel could be observed at the fully cross-linked density, and its mechanical properties could be modulated by the amount of the macrotricyclic host added to the system. Moreover, the supramolecular polymer gel showed acid/base- and thermo-induced reversible gel-sol transitions. Additionally, the supramolecular polymer gel could also be employed for the encapsulation and controllable release of squaraine dyes, which might find potential applications in materials science.
