| Research Abstract |
Amphiphilic block copolymers consisting of a hydrophobic polyisocyanate chain with an optically active terminal group with a hydrophilic poly(ethylene glycol) chain were successfully synthesized. It was demonstrated that the copolymers formed spherical micelles in aqueous solution and the helical sense excess of the polyisocyanate chain was amplified in the core of the micelles over that in THF due to the reduction in population of the helical reversals. Amphiphilic block copolymers consisting of a hydrophobic optically active polythiophene chain with a hydrophilic poly(acrylic acid) chain were also synthesized and these copolymers were found to self-assemble into micelles in water and exhibit a characteristic ICD in the π-π^^* transition region due to the formation of supramolecular chiral aggregates in the core.
