Outline of Final Research Achievements

We organized macroscopic arrays from colloidal liquid crystals of niobate nanosheets through hierarchical organization of the nanosheets. The nanosheet arrays were prepared by a two-stage process which involves growth of the liquid crystalline domains and orientation of the grown domains under an electric field. The array structure was regulated by the domain size and relative directions of the electric field and gravity. Typically, net- and stripe-shaped arrays with characteristic length sub-mm were obtained. Dynamic property of the nanosheet liquid crystal endowed temporal nature with the array structures. Photocatalytic dye decomposition in the stripe-shaped nanosheet array reflected the unidirectional orientation of the nanosheets forming the stripes.
