Abstract

Abstract : Multi‐responsive amphiphilic supramolecular diblock copolymers are prepared by a facile new method via the cooperative complexation between a water‐soluble pillar[10]arene and paraquat‐containing polymers in water. Multi‐responsive polymeric micelles prepared from this diblock copolymer can be used in the rate‐tunable controlled release of small molecules depending on the type of single stimulus and the combination of various stimuli. Abstract : Herein, for rate‐tunable controlled release, the authors report a new facile method to prepare multiresponsive amphiphilic supramolecular diblock copolymers via the cooperative complexation between a water‐soluble pillar[10]arene and paraquat‐containing polymers in water. This supramolecular diblock copolymer can self‐assemble into multiresponsive polymeric micelles at room temperature in water. The resultant micelles can be further used in the controlled release of small molecules with tunable release rates depending on the type of single stimulus and the combination of various stimuli.
