Electro-optic and dielectric investigations of a perfluorinated compound showing orthoconic antiferroelectric liquid crystal

► V-shaped switching in a 4 μm indium tin oxide coated, planar electro-optical cell.► An interesting phase comes in the temperature region between 74 °C and 84 °C. ► PL-mode, PH-mode, Goldstone-like mode, Goldstone mode and soft mode in OAFLC ► X-mode inside the region of antiferroelectric and electroclinic effect
