Used as a key building block in Suzuki-Miyaura cross-coupling reactions, this compound enables the synthesis of conjugated polymers and organic electronic materials. Its dual boronate ester groups react selectively with aryl halides, making it valuable for constructing extended π-conjugated systems used in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). It is also employed in the preparation of covalent organic frameworks (COFs) due to its rigid, planar structure and ability to form stable C–C bonds under mild coupling conditions.
