Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport materials for OLEDs (organic light-emitting diodes). Its brominated structure allows for further functionalization via cross-coupling reactions, making it valuable in synthesizing conjugated molecules for optoelectronic devices. Also employed in the preparation of host materials in phosphorescent OLEDs due to its favorable triplet energy and thermal stability. Additionally, it finds use in the research of perovskite solar cells as a building block for hole-transporting layers.
