Research Abstract |
We have synthesized novel bent-core liquid crystal materials by using 1,7-dihydroxynaphthalene and aklylthio terminal chain groups. A novel SmAP phase was observed where the polarization is lying parallel to the layer by extention to seven rings mesogen with 1,7-naphthalene core, which clearly showed a possibility to the application to in-plane switching mode. Furthermore, in the system which 1,7-naphthalene is combined with alkylthio terminal group, a novel switchable columnar phase was detected. The formation of novel columnar phase was understood by a high layer curvature due to the small bent angle structure of molecular design, which provides further scientific interests it self in addition to the anticipation to application of LC display.
