| Outline of Final Research Achievements |
An amphiphilic diblock copolymer PMEO-b-PAz, which was consist of a liquid crystalline azobenzene derivative methacrylate and an oligo(ethylene oxide) methacrylate, was synthesized by two-step atom transfer radical polymerization method. PMEO-b-PAz exhibited lyotropic liquid crystallinity in water system. In a spincast film of PMEO-b-PAz hybridized with silica or titania, a lyotropic liquid crystalline lamellar phase of the diblock copolymer aligned spontaneously perpendicular to the substrate plane due to thermal annealing process. We also attained to obtain a nanoporous metal oxide film with vertical alignment by removal of the organic component from the spincast film. Furthermore, the vertically-aligned nanoporous titania film had a potential for an anode of a dye-sensitised solar cell.
