A large number of ferroelectric dopants incorporating a chiral lactate unit, -OC*H(CH3)CO2-, have been synthesized and extrapolated values of Ps as high as 160 nC cm-2 have been found, although many of these compounds did not show any liquid crystal behavior.Terphenyls and laterally fluoro-substitued terphenyls incorporating the chiral lactate unit have also been synthesized, and in one case, a ferroelectric host material with an S*C phase and a Ps value of 124 nC cm-2 was obtained.Compounds containing two chiral units (one of which was a chiral lactate unit) were also synthesized in which the two chiral units were either directly linked or separated by a phenyl ring; the latter compounds gave very high Ps values (199 nC cm-2).The effect of molecular structure on Ps, tilt angle and phase behavior is discussed for both the mono-lactates and the di-chiral compounds.An outline (with references) of the experimental procedures used to prepare these compounds is also given.
