| Outline of Final Research Achievements |
Various kinds of bent-shape LC molecules were designed and prepared to investigate their physical and structural properties in detail. Finally, Cubic-hexagonal columnar-B2 or B7 phase transition behavior was confirmed that potentially could be applied for a FLC display material. Especially, the hexagonal columnar phase also showed a switchable behavior. It shows that the cubic phase might be switchable if a further modification in molecular structure will be made. Furthermore, a nematic phase that has a long-range periodic order was discovered by a design of novel LC mesogen. This nematic phase differs from the conventional nematic phase that can open the possibility of further applicable usage of nemtatic phase.
