| Abstract: | A stimuli-responsive supramolecular polymer network has been constructed based on the host-guest interactions between the copolymer poly-P5]A with pendent pillararene units and bis(sulfonium) diction guest G2. The formation mechanism of the supramolecular polymer network has been explored by the intensive study. With the addition of the competitive molecules and heating, the supramolecular polymer network could be dissociated and lead to clear changes in NMR spectroscopy and viscosity property. |
