Abstract
For the development of stimuli-responsive polymers, a series of novel thermo-responsive azobenzene-based supramolecular dendronized copolymers (4-(4′-(3, 4, 5-tris (2-(2-methoxyethoxy) ethoxy) benzyloxy) phenylazo) benzyl methacrylate) x -co-(N-Vinyl Pyrrolidone)y (PTEO2Azo x -co-PVP y ) have been successfully synthesized. We have investigated how the effects of temperature, content of azobenzene moiety, concentration, type and concentration of salt on the phase-transition behaviors of the dendronized copolymers, and the dendronized copolymers PTEO2Azo x -co-PVP y all showed the remarkably thermo-responsive phase-transition behaviors.
