Outline of Final Research Achievements

Liquid crystalline (LC) polymer materials were designed to realize the effective control of their organized structures for dynamic alignment of inorganic nanorods. It was revealed that the introduction of non-LC alkyl side-chains into nematic LC polymers promotes the interaction of functional small molecules with side-chain LC mesogens by improving the affinity of the molecules with the LC polymers. It was also demonstrated that the photo-responsive behaviors of the side-chain mesogens in sub-100nm-thick thin films could be promoted by the assistance of small LC molecules. The results led to the underlying technologies of the dynamic alignment control of inorganic nanorods.
