Used as a specialty building block in organic synthesis, particularly in the development of high-performance polymers and functional materials. Its rigid aromatic structure combined with fluorinated segments enhances thermal stability and chemical resistance in resulting polymers. Commonly applied in the production of advanced electronic materials, including semiconductors and dielectrics, due to its ability to improve moisture resistance and electrical insulation. Also investigated as a ligand or modifier in catalysis, especially in palladium-mediated coupling reactions. Its unique hydrophobic and electronic properties make it suitable for use in fuel cell membranes and optoelectronic devices.
