研究実績の概要 |
In order to develop a new type of ferroelectric liquid crystals (FLCs) having columnar LC geometries, by using the technology of disk-rod hybrid columnar assembly realized by supramolecular polymerization in LC media, which is developed in Aida group, I started to synthesize an appropriate monomer. The synthesis of the monomer involves the incorporation of a bent-core molecular motif as a side chain of the core part of the monomer. In the core part, a hydrogen-bonding motif was employed. So far, I have successfully synthesized the side chain parts and the core parts. After coupling these units, the monomer for supramolecular polymerization is completed.

2: おおむね順調に進展している
理由
For synthesizing the monomer, a multi-step synthesis of more than 10 steps are needed, and was expected to spend the first year for that.

今後の研究の推進方策 |
In the next year, I will finish the final step for the monomer synthesis and investigate the LC behavior upon mixing various rod-shaped LC molecules. The characterization method includes X-ray diffraction, differential scanning calorimetry, polarized optical microscopy. Then, I will move on to the electrical response of the material. In this case, E-field response of both columnar orientation and polarization will be investigated. Finally, I will carry out the feasibility study of the material for ferroelectric devices.
