| Outline of Final Research Achievements |
This work deals with the creation of microgel star polymers with designed nano-space/domains for unique functions. For this, novel synthetic strategies were developed via the intramolecular crosslinking of self-folding amphiphilic random copolymer unimer micelles in water or the dynamic covalent or physical crosslinking of hydrogen-bonding block or random copolymer micelles in organic or aqueous media. Importantly, the primary structure of the copolymer precursors (prepared by living radical polymerization) and micelle size are directly reflected to the size and structure of resulting star polymers; thus, on-target control of three-dimensional structure and spaces in microgel star polymers was successfully achieved. Star polymers with designed nanospaces served as efficient nanoreactors for living radical polymerization and nanocapsules for selective molecular recognition. Additionally, precision self-assembly systems with amphiphilic random copolymers in water were also developed.
