Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for the construction of conjugated organic materials. Commonly applied in the development of organic semiconductors, OLEDs (organic light-emitting diodes), and perovskite solar cells due to its ability to form stable carbon-carbon bonds with aryl halides. Its boronate ester groups enable efficient and selective coupling, making it valuable in creating hole-transporting or emissive materials in optoelectronic devices. Also employed in the synthesis of functional polymers and small molecules for advanced electronic applications.
