摘要： The new LC media exhibit a ferroelectric nematic phase at ambient temperature. They comprise at least one or more compounds selected from each of formula IA, of formula IB and of the group of formulae IC-1/IC- 2/IC-3, in which the variable groups have the meanings indicated in the text and in the claims. The mixtures are useful for electro-optics, electronics, electromechanic and other applications for materials with very high dielectric permittivity and other energy-saving applications.

摘要： The new media exhibit a ferroelectric nematic phase preferably at ambient temperature. They preferably comprise one or more compounds selected from the group of compounds of formulae IA, IB and 1C, in which the variable groups have the meanings indicated in the text and in the claims. Use of the media for providing ferroelectric nematic materials and a method of operation of an electro-optical device are presented. The media may be useful for energy-saving displays and electrical appliances.
