| Research Abstract |
Mesoporous silicas with tetrahedrally close-packed (TCP) structures display rich structural diversity. We have investigated their structural changes by electron microscopy. The results were as follows; (i) in anionic surfactant system, we have found and characterized Pm-3n (A15), Cmmm (H), P4_2/mnm (σ) and P6/mmmstructures, (ii) we have found and characterized mesoporous silica quasicrystals with dodecagonal symmetry, which show two dimensional aperiodic tilings of squares and equilateral triangles on the mesoscale.
