| Outline of Final Research Achievements |
Our research group has discovered a new liquid crystalline material that exhibits ferroelectricity even though it is a fluid. However, the mechanism of the appearance of ferroelectricity has not been clarified, and the temperature range of the appearance is considerably higher than room temperature, so there have been some problems in its application. In this study, we synthesized novel liquid crystal compounds that exhibits ferroelectricity, investigated the correlation between molecular structure and ferroelectricity, and clarified that a dipole moment of a certain magnitude in the direction of the molecular long axis is important. In addition, we succeeded in developing a material that exhibits ferroelectricity near room temperature by utilizing the eutectic melting phenomenon in mixed systems. Furthermore, we succeeded in visualizing the orientation state of molecules in a domain using a device of our own design.
