New dopants for induced ferroelectric SC* phases containing 1,3-dioxolan-2-one as a chiral heterocycle

Abstract
The synthesis, phase behaviour and spontaneous polarization of a new class of chiral dopants for induced ferroelectric phases of general structure 6 and 9, possessing a 1,3-dioxolan-2-one ring, are described. One of the new compounds exhibits a SA phase. When the chiral ring system is positioned terminally to the mesogen (6) the cis disubstituted compounds show higher induced spontaneous polarization than those with an analogous trans configuration.
