摘要：

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 degrees. In addition, both of the enantiomers exhibited an isotropic-isotropic liquid transition just above the transition to the liquid crystalline state.
