Used as an intermediate in organic semiconductor materials, particularly in the synthesis of high-performance hole-transport materials for OLEDs and perovskite solar cells. Its brominated structure allows for further functionalization via cross-coupling reactions, enabling tailored electronic properties. Commonly employed in the development of blue emitters and host materials in light-emitting diodes due to its good thermal stability and triplet energy characteristics. Also utilized in the fabrication of photovoltaic devices where carbazole derivatives enhance charge transport and device efficiency.
