Enantiotropic ferroelectric nematic phase in a single compound.

The ferroelectric nematic phase became the centre of interest of scientists because of its unique physical properties. The uniqueness of this particular phase results in its monotropic character in all known N F materials. Here we present the very first example of a compound with an enantiotropic ferroelectric nematic phase. Compound 3JK is complementary with already well known N F materials, i.e. RM734 and DIO and is characterized by moderately high dielectric anisotropy.
