Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl and heteroaryl frameworks. It serves as a key building block in the development of organic electronic materials, including organic light-emitting diodes (OLEDs) and hole-transport materials for perovskite solar cells. Its carbazole core provides good thermal stability and hole-transport properties, making it valuable in designing functional materials for optoelectronic devices. Also employed in the synthesis of conjugated polymers and small molecules for use in organic semiconductors.
