Abstract
New series of chiral liquid crystalline materials with the same rigid core with keto group and a various number of (S)-lactate groups in the chiral part of the molecule have been studied by DSC, X-ray, electro-optics and dielectric spectroscopy. All compounds contain branched terminal alkyl chain derived from (S)-2-methylbutanol. The influence of the lactate number on mesogenic behavior of those compounds has been studied. All compounds show the paraelectric SmA phase and the ferroelectric SmC* phase in a rather wide temperature range. The antiferroelectric SmC*A phase was detected for the compound possessing two lactate groups. A polar field-induced smectic phase have been observed by electro-optic studies.
