Mesogenic properties of liquid crystals having a chiral semiflexible joint

Article abstract of DOI:10.1080/10587259408038653

Two homologous 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 reentrant system are discussed. On 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. Triple divergence of the pitch in the cholesteric phase of a pure compound is observed.
