A Multiresponsive Amphiphilic Supramolecular Diblock Copolymer Based on Pillar10arene/Paraquat Complexation for Rate-Tunable Controlled Release

摘要

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 pillar10arene 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.
