Used as a key intermediate in organic optoelectronic materials, particularly in the synthesis of high-performance host materials for blue phosphorescent OLEDs. Its rigid molecular structure and strong electron-donating properties enhance device efficiency and thermal stability. Commonly employed in emissive layer formulations to improve charge transport and prevent exciton quenching. Also explored in perovskite solar cells as a hole-transporting material due to its suitable energy levels and film-forming characteristics.
