Used in organic synthesis as a key building block for constructing conjugated polymers and small molecules in optoelectronic materials. Commonly employed in Suzuki-Miyaura cross-coupling reactions to develop organic semiconductors for applications in OLEDs, organic photovoltaics (OPVs), and field-effect transistors (OFETs). Its boronic acid groups enable efficient carbon-carbon bond formation, facilitating the creation of extended π-conjugated systems. Also utilized in the design of fluorescent sensors and dyes due to its rigid aromatic framework and tunable electronic properties.
