Used primarily as a building block in organic synthesis, especially in the development of advanced materials. Its rigid, tetra-substituted ethene structure with fluorinated aryl groups makes it valuable in the design of organic semiconductors and optoelectronic materials. It is employed in the synthesis of fluorescent probes and aggregation-induced emission (AIE) luminogens due to its ability to exhibit strong emission in the solid state. Also utilized in pharmaceutical research as a scaffold for drug discovery, leveraging the metabolic stability and enhanced lipophilicity provided by the fluorinated aromatic rings. Its unique geometry and electronic properties support applications in liquid crystals and supramolecular chemistry.
