Anticlinic Antiferroelectric Smectic Liquid Crystal Formed by an Asymmetric Banana-Shaped Molecule

Switching axis: A new banana‐shaped molecule forms the SmCAPA phase in the ground state and SmCSPF phase on applying an electrical field. The optic axis of such banana‐shaped molecules is oriented parallel to the rubbing direction under zero‐field state. The picture shows the proposed three polar st...

Description
Summary:Switching axis: A new banana‐shaped molecule forms the SmCAPA phase in the ground state and SmCSPF phase on applying an electrical field. The optic axis of such banana‐shaped molecules is oriented parallel to the rubbing direction under zero‐field state. The picture shows the proposed three polar structures in the B2 phase: two different colors indicate that the mesogenic structure is asymmetric.
