| 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.
