Amplification of twisting power in chiral mesophase by introducing achiral rod-like compound with ester group
The helical pitch of a chiral nematic (cholesteric: Ch) liquid crystal (LC) became shorter if an achiral compound 1 was added to a chiral host. This unusual behavior characteristic to ester compounds can be explained by the ability of the ester compound 1 to form non-planar conformations.
