Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of organic semiconductors and optoelectronic materials. Its carbazole moiety provides hole-transport properties, making it valuable in the development of OLEDs (organic light-emitting diodes) and perovskite solar cells. The boronate ester group enables efficient carbon-carbon bond formation, allowing for the construction of complex conjugated systems used in organic electronics and photovoltaics. Commonly employed in the fabrication of emissive or host materials in display technologies and lighting applications.
