| Outline of Final Research Achievements |
It is necessary to maintain a nano-level polarized state in liquid crystal compounds to realize high-density memory devices with electric field response, but no practical compounds have been found at present. In this study, we have realized ferroelectricity (a property that polarizes in response to an external voltage and maintains its polarized state even after voltage removal) in an optically active urea derivative. Furthermore, by comparing the polarity and stability of optically active and optically inactive derivatives, we have succeeded in elucidating the mechanism for generation of the ferroelectricity.

| Academic Significance and Societal Importance of the Research Achievements |
生体内で行われているような「ナノの世界で構造体を形成すること」が今後の産業や医療の技術において、革新的な発展を生むと考えられる。本研究の成果は、非接触で液晶シート上へのナノレベルの情報記録をする基礎技術の成功であり、１）ナノレベルの情報記録、２）重合性分子の配置、３）光重合によるナノ構造体の構築、という方法論の第一段階の達成に相当する。さらに、本研究では、新しい有機圧電体を作製する方法の開発にも成功している。
