Used primarily in organic synthesis, especially in Suzuki-Miyaura cross-coupling reactions to construct biaryl and heterobiaryl compounds. Its boronic acid functionality enables the formation of carbon-carbon bonds, making it valuable in the development of organic electronic materials such as OLEDs and semiconducting polymers. The carbazole and biphenyl moieties contribute to high thermal stability and hole-transport properties, which are advantageous in optoelectronic devices. Commonly employed in the synthesis of conjugated materials for use in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs).
