PB39 ブルー相IIIの安定性に及ぼす液晶オリゴマーの影響(液晶ディスプレイ,ポスター発表,2015年日本液晶学会討論会)

抄録

We prepared some BPIII materials doped with 3.4 wt% of a liquid crystal oligomer and investigated their phase transition behavior. A linear dimer in which phenylpyrimidine and cyanobiphenyl units are connected via an octamethylene spacer was found to raise the Iso-BPIII transition temperature by 26.6 K. A temperature range of BPIII was extended to more than 80 K by polymer-stabilization. The PS-BPIII exhibited fast response and hysteresis-free switching at room temperature.
