Used as a high-performance organic semiconductor material in OLED devices, particularly as a host compound in blue phosphorescent emissive layers. Its rigid, twisted molecular structure provides excellent thermal stability and high triplet energy, enabling efficient energy transfer to blue dopants while suppressing exciton quenching. Commonly employed in display and lighting technologies where efficiency, color purity, and device longevity are critical. Also explored in perovskite solar cells as a hole-transporting material due to its favorable energy level alignment and film-forming properties.
