Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport materials for perovskite solar cells. Its aromatic structure and bromine functionalization allow for further cross-coupling reactions, enabling the synthesis of conjugated polymers or small molecules with tailored electronic properties. Also employed in the preparation of host materials for phosphorescent OLEDs due to its high triplet energy and thermal stability. The compound’s carbazole core contributes to good film-forming ability and charge transport characteristics in optoelectronic devices.
