Used in organic semiconductor materials, particularly in the development of organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its structure supports efficient π-π stacking and charge transport, making it valuable as a building block in conjugated polymers and small molecules for optoelectronic devices. The electron-withdrawing nitrile group and the heavy bromine atom facilitate functionalization through cross-coupling reactions, enabling fine-tuning of electronic properties. Commonly employed in synthesis of donor-acceptor type copolymers for high-performance organic electronics.
