Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. It serves as a key building block for constructing conjugated organic materials such as organic semiconductors, light-emitting diodes (OLEDs), and photovoltaic materials. Its boronate ester groups allow for efficient and selective coupling with aryl halides under mild conditions, making it valuable in the development of complex aromatic and polyaromatic systems for electronic and optoelectronic applications. Also employed in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) due to its rigid, planar structure and reactive handles.
