Direct transition from SA to antiferroelectric, ferroelectric or unknown phases of diastereomeric liquid-crystalline molecules with varying enantiomeric purities

Abstract

The phase sequences of diastereomeric α-trifluoromethyl-β-methyl-substituted liquid-crystalline molecules critically depend on the enantiomeric purities (% ee) not only for ul- but also for lk-diastereomers, to show eventually an unknown phase in the racemic region of either an ul- or an lk-diastereomer.
