PB19 キラルメソゲンの空間配置制御によるブルー相の安定化(化学・材料,ポスター発表,2012年日本液晶学会討論会)

抄録

To investigate the influence of molecular structure of dopants for stabilization of blue phases, we prepared dopant compounds which had different spatial arrangements of chiral mesogens, and they were added to 5CB, respectively. The mixture of 5CB with a tripodant compound showed the widest temperature range of the blue phase in this series, and compounds possessing two mesogens at o-, m- and p- positions of benzenes indicated a clear difference in the temperature range of the blue phase. We suggested the mechanism for stabilization of the blue phases.
