| Outline of Final Research Achievements |
The synthesis of well-defined multicyclic polymers (figure-eight-shaped and trefoil-shaped homo- and copolymers) was achieved by the combination of living/controlled polymerization and click cyclization. The effect of multicyclic architecture on the micelle properties was also investigated. We have synthesized the well-defined figure-eight-shaped and trefoil-shaped polyethers using the combination of the t-Bu-P4-catalyzed ring-opening polymerization of epoxides and intramolecular click cyclization. The strategy should also be effective for the synthesis of amphiphilic figure-eight-shaped and trefoil-shaped block copolyethers. In order to investigate the aggregation behavior of the amphiphilic block copolyethers, the hydrodynamic diameter and the critical aggregation concentration were determined by dynamic light scattering and fluorescence technique using pyrene, respectively.
