Used as an intermediate in organic semiconductor materials, particularly in the synthesis of conjugated polymers for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its bromine functionality allows for palladium-catalyzed cross-coupling reactions, enabling the construction of complex aromatic structures. The octyl chain enhances solubility in organic solvents, improving processability in thin-film device fabrication. Commonly employed in the development of hole-transport materials and blue emitters in display technologies.
