High performance dual frequency liquid crystal compounds

Abstract

Some high birefringence ester liquid crystal compounds with cyanate or isothiocyanate polar groups were investigated, the relaxation frequency of which is in the kilo‐Hertz region. These compounds are useful for formulating dual‐frequency liquid crystal (DFLC) mixtures. The dielectric relaxation and electro‐optical properties of these compounds were characterised. Potential applications of these compounds for DFLC mixtures to meet different requirements are discussed.
