| Research Abstract |
Novel methodologies for precise control of hierarchical structures of siloxane-based materials were developed. Gigantic siloxane oligomers whose structures are defined in a molecular level were synthesized by stepwise silylation of a cage-type siloxane oligomer. Colloidal siloxane nanospheres and nanorods were synthesized by self-assembly of siloxane-based block copolymers. Highly dispersible mesoporous silica nanoparticles which are useful as building blocks of hierarchical structures were prepared. The sheet-like zeolite was synthesized from the corresponding layered silicate by a retro-synthetic method. These methodologies will contribute to stepwise construction of siloxane-based materials with hierarchical structures.
