Synthesis of a smart Janus-like supramolecular polymer based on the host-guest chemistry and its self-assembly

摘要

We report on the double stimuli-responsive self-assembly of a Janus-like supramolecular polymer based on the host-guest chemistry. It is constructed by the noncovalent coupling between a hyperbranched PMAA with an apex of an adamantane (Ad) group and a hyperbranched PNIPAAm with an apex of a beta-cyclodextrin (beta-CD) group. Upon adjusting the solution pH or temperature, the supramolecular polymer can reversibly self-assemble in solution.
