Abstract

Achiral bend-shaped molecules are known to show chiral liquid crystal phases, which have attracted attention as a new formation mechanism of the chiral molecular aggregates without molecular chirality. Furthermore, de Gennes et al. theoretically predicted that dumbbell-shaped molecules having bulky substituent at their both ends could easily induce helical structure due to an asymmetric interaction in molecular packing. In this study, a novel achiral dumbbell-shaped molecule was synthesized and the effect of enhancing chirality of liquid crystal by adding the molecule to a chiral nematic phase was investigated. By the addition of the dumbbell-shaped molecule to a chiral nematic phase, the helical pitch of the chiral nematic liquid crystal is decreased. This result indicates that the molecule prevents inducing chirality in liquid crystals.
