Used primarily in liquid crystal formulations for advanced display technologies. Its rigid molecular structure and fluorine substitutions enhance thermal stability and improve dielectric anisotropy, making it suitable for high-performance liquid crystal displays (LCDs), especially in wide-temperature or fast-response applications. The ethynyl linkage and trans-cyclohexyl group contribute to high birefringence and good alignment properties, which are critical for achieving sharp images and low driving voltages in display panels. Commonly found in mixtures for TFT-LCDs and other active-matrix displays.
