Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport materials for OLEDs (organic light-emitting diodes). Its bromine functionality allows for further cross-coupling reactions, enabling the synthesis of larger conjugated systems. Also employed in the preparation of carbazole-based polymers and small molecules for photovoltaic devices due to its good thermal stability and electron-donating properties. Commonly found in research related to blue-emitting materials and host compounds in emissive layers.
