| Outline of Final Research Achievements |
Relaxers show a slow change of relatively large dielectric constants in wide temperature range. In this study, we investigated molecular materials showing rotation and/or large amplitude motion in the crystalline state. These compounds should become a basis of future moleculrar relaxers. Relaxation of dielectric constants were obsreved several crystals. Among others, the crystal composed of adamantane derivative and dibenzo[18]crown-6 showed a dielectric response based on coupling of molecular lotation and displacement of adamantane part and benzene rings, respectively. These compousd are the good basis for developing molecular relaxers.
