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 sensors and optoelectronic devices due to its favorable electronic properties and chemical stability.
