Used in organic semiconductor materials due to its electron-rich aromatic structure, enhancing charge transport in thin-film transistors. Commonly incorporated into conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid backbone improves thermal stability and film morphology in electronic devices. Also serves as a building block in synthesizing more complex heterocyclic compounds for pharmaceutical and agrochemical research.
