Abstract
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, electro-mechanic and other applications for materials with very high dielectric permittivity and other energy-saving applications.
