Application

This compound serves as a key intermediate in the synthesis of advanced liquid crystal materials for display technologies. Researchers utilize its rigid biphenyl-ethynyl structure to modify mesomorphic properties in nematic LC formulations. The electron-withdrawing fluorine atoms and ethoxy group make it particularly useful for tuning dielectric anisotropy in electro-optical applications. It has shown promise in organic semiconductor research due to its extended π-conjugation system.
