Outline of Final Research Achievements |
Plastic crystals are soft solid materials. Depending on their constituent particles, they can be classified as ionic or molecular plastic crystals. In both types, the constituents are isotropically rotated at each crystal-lattice point in either a NaCl- or CsCl-type cubic system. The particle has fused orientation, and the gravity point of each particle is ordered. This situation is the opposite of that seen in liquid crystals. In this study, 16 crystals were constructed in a new region of ionic plastic crystal, where the cations and anions are held together by weak interactions. In addition, these crystals showed high conductivities of ca. 10-3 S cm-1 at around room temperatures.
