Used as a key building block in organic semiconductors, especially in the synthesis of conjugated polymers for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its boron-based functional groups enable efficient Suzuki-Miyaura cross-coupling reactions, allowing for precise construction of complex π-conjugated systems. Commonly employed in the development of donor-acceptor copolymers to fine-tune electronic properties such as bandgap and charge carrier mobility. Also applied in the fabrication of sensors and light-emitting diodes (OLEDs) due to its stability and electronic compatibility in thin-film devices.
