제목 Amphiphilic Triblock Copolymer Brushes for their Supramolecular Assembly
초록 Amphiphilic molecular brushes (MBs) composed of a linear backbone with densely grafted polymeric side chains have been of great interest because of their unique self-assembly behavior. We report herein synthesis of positively- or negatively charged amphiphilic triblock MBs and their polyelectrolyte complexed nanostructures via noncovalent interactions. Linear amphiphilic triblock copolymers (ATCs) as macromonomers were synthesized from a chain transfer agent with a norbornene end group by reversible addition-fragmentation chain transfer polymerization, and their MBs composed of poly(norbornene) as backbone and ATCs as side chains were synthesized via ring-opening metathesis polymerization. The MBs self-assembled into cylindrical micelles while vesicles were formed via complexation between two oppositely charged MBs. Conclusively, this work would be useful for developing functional nanomaterials as drug delivery carriers.
