Used as a high-performance organic semiconductor in organic field-effect transistors (OFETs) and organic photovoltaic (OPV) devices due to its excellent charge carrier mobility and thermal stability. Its planar molecular structure and strong intermolecular interactions enhance π-π stacking, improving electron delocalization and device efficiency. Commonly employed as a donor material in bulk heterojunction solar cells, where it contributes to higher power conversion efficiencies. Also explored in perovskite solar cells as a hole-transport layer owing to its suitable energy level alignment and film-forming properties. Its bromine substituents allow for further functionalization via cross-coupling reactions, enabling tailored modifications for specific electronic applications.
