Abstract

Two homologue series of mesogenic enantiomers with chiral semiflexible joint, - C^*H(CH₃)CH₂COO-, are examined. High twist power and presence of blue phases with short lattice period are found for eleven examined compounds. Some effects of chirality in the re-entrant system are discussed. On the phase diagram of enantiomers the SmA_d phase area is shifted toward longer homologues as compared to racemates. In result, an island of the SmA_d phase in the cholesteric sea exists on binary phase diagrams of R- and S- enantiomers.
