Used as a key building block in organic electronics, particularly in the synthesis of conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances electron delocalization and improves charge transport properties. Commonly employed in donor-acceptor type materials to tune bandgap and enhance luminescence efficiency. Also utilized in sensing applications due to its ability to coordinate with metal ions, enabling detection of specific analytes in chemosensors.
