Abstract

Chiral dopants induce a chiral nematic phase which has a helical molecular arrangement when they are added to a nematic liquid crystal. In this study, we synthesized new chiral dopants having biphenanthrene skeleton and investigated properties of helical twisting power in the nematic phase. As temperature increased, the helical twisting power of (S)-1-OH increased. This feature of helical twisting power has been hardly observed in the case of binaphtyl derivatives. It is suggested that the temperature dependence of helical twisting power of (S)-1-OH was attributed to hydroxyl group. Additionally, the helical sense of chiral nematic phase induced by (S)-1-OEt which adopted cisoid conformation was left-handed. It is found that the chirality transfer mechanism from biphenanthryl-type chiral dopants to host nematic liquid crystals was different from binaphthyl-type chiral dopants.
