As soft materials, liquid crystal (LC) and supramolecular dendrimers are self-assembling building blocks having numerous merits such as the ability to form a very small feature size (sub-10nm), various ordered phases, diversity in chemical functionality, and rapid construction of nano-structure with high ordering. The application areas of liquid crystals and supramolecules are optoelectronic materials, particle trapping, 3D microlens array, selective membranes, and novel nano-lithographic templates. Our group proceeds in-depth studies for supramolecules and liquid crystal self-assembly for nano-fabrication and try to use them in practical applications.>
