Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Serves as a building block for the preparation of conjugated materials used in organic electronics, such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its carbazole moiety provides good hole-transport properties and thermal stability, making it valuable in the development of semiconducting materials. Also employed in the synthesis of fluorescent dyes and sensors due to the inherent photophysical properties of the carbazole core.
