Low Viscous Compounds of Highly Nematic Character

Abstract

Abstract Mixtures of broad nematic temperature ranges that permit acceptably short switching times of electro-optical displays at −40°C can be composed of compounds of relatively low polarity and high transition temperatures from the nematic to the isotropic state (T NI. Structures combining 1,4-phenylene and trans-1,4-cyclohexylene rings are particularly suited for this purpose.
