This compound is primarily utilized as a chiral dopant in ferroelectric liquid crystal displays (FLCDs) to induce helical twisting power in smectic phases. It demonstrates exceptional compatibility with host LC mixtures for fast-switching reflective displays and spatial light modulators. Researchers employ it in electro-optic studies of flexoelectricity and spontaneous polarization in chiral smectic C phases. The material also finds niche applications in tunable photonic crystals and THz wave modulation devices due to its strong birefringence.
