1b09 新規含フッ素ビナフチル系キラル剤を用いた液晶ブルー相の特性評価(ソフトマター,口頭発表,2012年日本液晶学会討論会)

抄録

Fluorinated nematic liquid crystals (LCs) are used commonly as TFT-LC display materials because they show a low viscosity, a high voltage holding ratio and a high responsivity. Binaphthyl derivatives are well known as chiral dopants which show a large helical twisting power (HTP). In this study, we aim at the development of chiral dopants with a large HTP and a high solubility in the fluorinated nematic LC and designed novel fluorinated binaphthyl chiral dopants. In addition, we investigated properties of blue phases induced by adding the chiral dopant to the fluorinated nematic LC.
