Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of high-performance conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances π-conjugation and promotes strong intermolecular stacking, improving charge carrier mobility. Also employed in the preparation of functional materials for optoelectronic devices due to its electron-withdrawing properties and stability.
