Used as a high-performance organic semiconductor material in OLED devices, particularly as a host compound in blue phosphorescent and thermally activated delayed fluorescence (TADF) emitters. Its rigid, twisted molecular structure provides excellent thermal stability and high triplet energy, enabling efficient energy transfer and reduced efficiency roll-off. Commonly employed in display and lighting technologies where long operational lifetime and high color purity are required. Also explored in multilayer device architectures due to its good film-forming properties and compatibility with vacuum deposition processes.
