We report a transition from the ferroelectric nematic liquid crystal ($N_F$)phase to a lower-temperature, antiferroelectric fluid phase having reentrantisotropic symmetry ($I_A$), in the liquid crystal compound RM734 doped withsmall concentrations of the ionic liquids BMIM or EMIM. Even a trace amount ofionic liquid dopant facilitates the kinetic pathway for the transition from the$N_F$ to the $I_A$, enabling simple cooling to produce this isotropic fluidphase rather than resulting in crystallization. The $I_A$ was also obtained inthe absence of specific ionic liquid doping by appropriate temperature cyclingin three distinct, as-synthesized-and-purified batches of RM734, two commercialand one from our laboratory. An additional birefringent, lamellar-modulated,antiferroelectric phase with the director parallel to the layers, resemblingthe smectic $Z_A$, is found between the paraelectric and ferroelectric nematicphases in RM734/BMIM mixtures.
