Used as a key intermediate in organic light-emitting diodes (OLEDs), particularly in the fabrication of blue-emitting materials. Its structure supports high triplet energy levels, making it suitable for host materials in phosphorescent OLEDs. The bromine functionality allows for further chemical modification via cross-coupling reactions, enabling the synthesis of larger conjugated systems for enhanced charge transport and device efficiency. Also employed in the development of hole-transport materials and emissive layers in flat-panel displays and lighting devices.
