Used as a key intermediate in organic semiconductor materials, particularly in the synthesis of high-performance OLEDs and organic photovoltaics. Its brominated structure allows for efficient cross-coupling reactions, enabling the construction of complex conjugated systems. Commonly employed in the development of blue-emitting materials due to its stable carbazole core and suitable energy levels. Also utilized in research for hole-transport materials and perovskite solar cells, where its derivatization enhances device efficiency and thermal stability.
