Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing conjugated thiophene-based systems. These systems are essential in the development of organic semiconductors, conductive polymers, and materials for organic photovoltaics (OPVs). Its boronic acid functionality allows for mild and selective coupling with halogenated aromatics, making it valuable in the synthesis of complex organic molecules used in electronic and optoelectronic devices. Also employed in the preparation of functionalized polythiophenes, which find applications in sensors, field-effect transistors (FETs), and light-emitting diodes (OLEDs).
