摘要：A novel supramolecular hyperbranched polymer had been fabricated conveniently through host-guest recognition based on Cucurbit[8]uril in aqueous solution. The three branched monomer contained an azobenzene unit and a viologen moiety on each of its branch. The polymerization of the supramolecular polymer in water could be controlled by tuning the isomer ratio of azobenzene groups of the guest monomers upon the competitive irradiation of lights. In addition, the strictness of the structure could be adjusted by varying the molar ratio between host and guest monomers. Planar supramolecular network had been constructed by drying the solvent of the solution of supramolecular hyperbranched polymers on smooth plane. The research provided a promising way to conduct dual-responsive supramolecular polymerization. (C) 2017 Elsevier Ltd. All rights reserved.
