| Outline of Final Research Achievements |
Designing strategy of organic ferroelectrics has been examined in alkylamide-substituted benzene derivatives with discotic liquid crystalline property. The inversion of intermolecular amide-type hydrogen-bonding interaction within the column resulted in the dipole inversion and ferroelectricity. The ferroelectric hystereces behavior was affected by the molecular designs of number and position of introducing substituents on benzene core. The organic thin film ferroelectrics should be one of the essential molecular memory device, and one of the important designing strategy has been obtained from this project.
