Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct complex conjugated systems for optoelectronic materials. Commonly applied in the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). Its boronate ester groups enable efficient and selective coupling with aryl halides, making it valuable for building extended π-conjugated frameworks. Frequently employed in the synthesis of host materials for blue phosphorescent OLEDs due to its favorable triplet energy and hole-transport properties. Also used in the preparation of donor-acceptor type polymers and small molecules for solar cell applications.
