Used in organic electronics as a building block for conjugated polymers and small molecules in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid, linear structure enhances electron delocalization and charge transport. Also employed in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) due to its ability to form extended π-conjugated networks. Acts as a precursor in Sonogashira coupling reactions to construct complex aromatic systems for advanced materials research.
