Application

This fluorinated biphenyl derivative is primarily utilized as a key intermediate in the synthesis of advanced liquid crystalline materials for display technologies. Its unique fluorine substitution pattern enables fine-tuning of dielectric anisotropy and thermal stability in nematic or smectic phases. Researchers also employ it as a building block for fluorinated organic semiconductors, where its electron-withdrawing properties enhance charge transport characteristics. Additionally, it finds use in the development of specialty polymers with enhanced chemical resistance and low surface energy properties.
