| Outline of Final Research Achievements |
We synthesized porous carbon, porous silica, and tetrapod-shaped zinc oxide particles mimicking the disclination lines of cholesteric blue phase II that is one of frustrated liquid crystalline phases. And, when these synthesized inorganic structural materials were added to cholesteric liquid crystalline phases, which are not frustrated liquid crystalline phases, we found that these inorganic materials strongly affected the structures of the director field in the host liquid crystalline phases. In addition, to clarify the internal structure of the complexes of the inorganic materials and liquid crystalline phases in the future, we developed finite-differential time-domain simulation method for liquid crystalline phases and analyzed the light propagation behavior in a cholesteric liquid crystalline emulsion. Furthermore, we developed the synthetic method of polymer nanosheets in lyotropic liquid crystalline phases.
