New chiral dopants for FLC materials: optically active cyclic ethers

Abstract A series of new optically active cyclic ethers such as tetrahydrofurans, chromans and dihydrobenzofurans were synthesized, and their physical properties as a chiral dopant for FLC were investigated. Correlation between the the chemical structures and the physical properties, especially spontaneous polarization (Ps), are discussed and compared with that of the corresponding lactones.

Synthesis and properties of new optically active γ-lactones as chiral dopants for ferroelectric liquid crystals

Optically active α-aryl-γ-alkyl-γ-lactones were synthesized through the reaction of chiral 1,2-epoxyalkanes with the carbanion derived from 4-methoxyphenylacetonitrile or 4-methoxyphenylacetic acid and shown to be good chiral dopants for ferroelectric liquid crystals.

Correlation between absolute configuration of benzylic chiral centre and sign of spontaneous polarization of chiral dopants for ferroelectric liquid crystals

The absolute configuration of a polar-group-substituted benzylic chiral carbon of a chiral dopant for ferroelectric liquid crystals is found to be predictable by the sign of spontaneous polarization of the ferroelectric liquidcrystalline mixtures containing the chiral dopant.
