New chiral dopants with an optically active six-membered ring for ferroelectric liquid crystals. Effect of direction of the dipole moment on spontaneous polarization

New chiral dopants containing an optically active six-membered ring with a cyano group were synthesized. New chiral dopants containing an optically active six-membered ring with an epoxy group were also synthesized and the effect of the direction of the dipoles on spontaneous polarization were discussed using them. The spontaneous polarization is thought to be influenced by the direction of the dipoles of the chiral moiety.
