(1) In crystalline solids, atoms or molecules are orderly arranged in a lattice whereas in liquids they lose such order and instead show a fluidity. Liquid crystals are an intermediate state between those two states, having both structural order and fluidity but partially. However, such intermediate situation is closely connected with their many attractive properties such as high responsivity with external stimuli such as electric field or light, high strength against deformation, self-healing, etc. Among various liquid crystals, we are focussing attention to the bicontinuous cubic phases. Elucidation of the molecular packing state and development of various functionalities are our aim of research.

(2) Polymers having two or more chemically incompatible segments form various structures and exhibit properties based on their structures. Ionomers and block polymers are one of such category. Our aim is elucidation of formation mechanism for such amazing microphase-separated structures and development of new functionalities.
