Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of conjugated organic materials for optoelectronic devices. Commonly employed in the preparation of organic semiconductors, fluorescent dyes, and luminescent compounds. Its boronate ester groups facilitate efficient carbon-carbon bond formation, making it valuable in pharmaceutical and agrochemical research for building complex aromatic frameworks. Also applied in polymer chemistry to construct well-defined π-conjugated polymers used in OLEDs and organic solar cells.
