Used as an intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its structure supports high thermal stability and efficient hole transport, making it valuable in designing host materials for phosphorescent OLEDs. Also employed in the synthesis of conjugated polymers and small molecules for optoelectronic applications due to its extended π-system and ease of functionalization at the bromine site.
