Used as an intermediate in organic synthesis, particularly in the preparation of phosphorescent materials for OLEDs (organic light-emitting diodes). Its bromine functionality allows for palladium-catalyzed cross-coupling reactions, enabling the construction of complex conjugated systems. Commonly employed in the development of host materials for blue-emitting OLED devices due to its high triplet energy and good thermal stability. Also utilized in the synthesis of charge-transport materials and as a building block in optoelectronic materials research.
