Used as an intermediate in organic semiconductor materials, particularly in the synthesis of hole-transport materials for OLEDs (organic light-emitting diodes). Its bromine functionality allows for further cross-coupling reactions, enabling the construction of larger conjugated systems. Commonly employed in the development of blue-emitting hosts and in perovskite solar cells due to its good thermal stability and ability to form stable radical cations. Also utilized in the preparation of carbazole-based polymers and dendrimers for optoelectronic applications.
