Used as an intermediate in organic semiconductor materials, particularly in the synthesis of hole-transport materials for OLEDs and perovskite solar cells. Its bromine functionality allows for easy coupling via palladium-catalyzed reactions, enabling the construction of larger conjugated systems. Commonly employed in the development of blue-emitting diodes and as a building block for high-triplet-energy hosts in phosphorescent devices. Also utilized in the preparation of carbazole-based polymers and dendrimers for optoelectronic applications.
