Used as an organic semiconductor in optoelectronic devices due to its extended π-conjugated system. Commonly applied in organic light-emitting diodes (OLEDs) as a host material for blue phosphorescent emitters. Also serves as a building block in covalent organic frameworks (COFs) for catalysis and gas storage. Exhibits good thermal stability and hole-transport properties, making it suitable for use in perovskite solar cells and thin-film transistors. Its nitrogen-rich structure enhances electron-donating ability and intermolecular interactions, improving device efficiency.
