Used primarily in organic semiconductor materials, this compound serves as a key intermediate in the synthesis of conjugated polymers for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its rigid, planar structure enhances π-electron delocalization, improving charge carrier mobility in thin-film electronic devices. It is also employed in the development of dye-sensitized solar cells due to its strong light absorption in the visible range and thermal stability under processing conditions. Additionally, its electron-withdrawing nitrile group facilitates energy level tuning when incorporated into donor-acceptor type polymers.
