Used as a key intermediate in organic semiconductor materials, particularly in the synthesis of high-performance electron-transport layers for OLEDs and perovskite solar cells. Its brominated structure allows for further functionalization via cross-coupling reactions, enabling precise tuning of electronic properties. The rigid, planar framework enhances charge carrier mobility and device stability. Also explored in the development of non-fullerene acceptors for organic photovoltaics due to its strong absorption and suitable energy levels.
