Abstract
A novel diblock copolymer consisting of poly(vinylferrocene) (PVFc) and poly( N , N -diethyl-acrylamide) (PDEA) is synthesized via a combination of anionic and RAFT polymerization. The use of a novel route to hydroxyl-end-functionalized metallopolymers in anionic polymerization and subsequent esterifi cation with a RAFT agent leads to a PVFc macro-CTA (Mn= 3800 g mol −1 ; Ð= 1.17). RAFT polymerization with DEA affords block copolymers as evidenced by 1 H NMR spectros-copy as well as size exclusion chromatography (6400 ≤ Mn≤33700 g mol −1 ; 1.31 ≤ Ð 1.28). Self-assembly of the amphiph-ilic block copolymers in aqueous solution leads to micelles as shown via TEM. Importantly, the distinct thermo-responsive and redox-responsive character of the blocks is probed via dynamic light scattering and found to be individually and repeatedly addressable.
