Used as a key intermediate in organic semiconductor materials, particularly in the synthesis of high-performance conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances π-π stacking, improving charge carrier mobility. Also employed in the development of blue-emitting materials for organic light-emitting diodes (OLEDs) due to its favorable electronic properties. The bromine sites allow for easy functionalization via cross-coupling reactions, making it valuable in constructing complex aromatic systems for optoelectronic applications.
