Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport layers for OLED (organic light-emitting diode) devices. Its rigid aromatic structure enhances thermal stability and improves film formation in thin-film electronics. Also employed in the synthesis of host materials for blue phosphorescent OLEDs due to its high triplet energy level. Shows promise in perovskite solar cells as a dopant-free hole-transport molecule, offering improved device efficiency and stability.
