Outline of Final Research Achievements

New tiling patterns have been created from three component block terpolymers having polyisoprene(I), polystyrene(S) and poly(2-vinylpyridine)(P) as incompatible chemical species. Firstly, binary ISP terpolymer blends with different chain lengths in both two end blocks have been found to show 1) a new cylindrical structure whose rectangular I and P domains are aligned tetragonally and 2) two new tiling structures with large oblong unit cells. The latter tiling patterns can be regarded as approximants of a quasicrystalline tiling with decagonal symmetry. Secondly, a new nanoporous structure has been formulated from ISP/HM(poly(4-hydroxystyrene-b-methylmethacrylate) blend united via hydrogen bonding between P and H components. Furthermore, a photonic film has been created by selectively swelling P domain of a SP diblock copolymer with an ionic liquid as a solvent.
