Abstract
In this article we report the first example of a pair of symmetrically subs tituted chiral twin enantiomers that exhibit stable wide temperature range ferrielectric and antiferroelectric phases, and which have large tilt angle s of over 45 degrees. In addition, both of the enantiomers exhibited an iso tropic-isotropic liquid transition just above the transition to the liquid crystalline state.
