Abstract

In this article we report the first example of a pair of symmetrically substituted chiral twin enantiomers that exhibit stable wide temperature range ferrielectric and antiferroelectric phases, and which have large tilt angles of over 45°. In addition, both of the enantiomers exhibited an isotropic–isotropic liquid transition just above the transition to the liquid crystalline state.
