Used as a key intermediate in organic semiconductors, especially in the synthesis of conjugated polymers for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its boron-containing groups enable efficient Suzuki-Miyaura cross-coupling reactions, allowing for the construction of complex π-conjugated systems. It is valued for enhancing charge carrier mobility and improving the stability and performance of thin-film electronic devices. Commonly employed in donor-acceptor copolymers to tune bandgap and energy levels for better light absorption and electron transport.
