Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. Commonly applied in the development of organic semiconductors, particularly in hole-transport materials for OLEDs (organic light-emitting diodes). Its carbazole core provides good thermal stability and efficient hole mobility, making it valuable in optoelectronic devices. Also employed in the preparation of fluorescent sensors and functional polymers due to its ability to form stable boronate esters and participate in palladium-catalyzed transformations.
