Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing conjugated organic materials. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in the development of organic semiconductors, OLEDs (organic light-emitting diodes), and pharmaceutical intermediates. The carbazole moiety contributes hole-transport properties and thermal stability, which are advantageous in optoelectronic devices. It is also employed in the synthesis of functional polymers and small molecules for use in photovoltaics and sensors.
