Used as a key building block in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct conjugated organic frameworks. It serves in the preparation of organic semiconductors, light-emitting materials, and conjugated polymers for optoelectronic devices such as OLEDs and organic photovoltaics. Its boronate ester groups enable efficient and selective coupling with aryl halides, making it valuable in the synthesis of complex aromatic systems for advanced materials research.
