Synthesis and Characterisation of a Novel Thermoresponsive Dendronized Monomer Bearing Azobenzene Moiety

Abstract

Novel thermoresponsive dendronized monomer bearing azobenzene moiety, 4-(4′-(3, 4, 5-tris (2-(2-methoxyethoxy) ethoxy) benzyloxy) phenylazo) benzyl methacrylate, has been successfully synthesized. The chemical structures of intermediate compounds and dendronized monomer were confirmed by FTIR and 1H NMR. The phase transition behaviors of these intermediate compounds and dendronized monomer were investigated. These intermediate compound and dendronized monomer showed remarkably reversible thermoresponsive phase transition behaviors.
