Electrochemical redox responsive polymeric micelles formed from amphiphilic supramolecular brushes

摘要

The end-decorated homopolymer poly(E-caprolactone)-ferrocene threaded onto a p-cyclodextrin-functionalized main-chain polymer can form a class of amphiphilic noncovalent graft copolymers based on the host-guest interactions of the terminal groups on the side chains. These new supramolecular polymer brushes can further self-assemble into micellar aggregates that exhibit reversible assembly and disassembly behavior under an electrochemical redox trigger, which opens up a new route to building dynamic block copolymer topologies.
