Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLEDs (organic light-emitting diodes). Its rigid, planar structure enhances charge transport and improves device efficiency. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy level, enabling effective energy transfer to dopants. Also explored in perovskite solar cells as a hole-transporting material, contributing to improved stability and performance. Its nitrogen-containing aromatic framework supports strong film-forming properties and thermal stability, making it suitable for thin-film electronic devices.
