Used as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of conjugated organic materials such as organic semiconductors, luminescent polymers, and molecular frameworks for optoelectronic devices. Its symmetric structure and reactive boronate ester groups facilitate the formation of extended π-conjugated systems, making it valuable in the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and porous organic networks like covalent organic frameworks (COFs). Also employed in the preparation of sensors and functional materials requiring precise molecular architecture.
