Used as a high-performance host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its rigid, twisted molecular structure provides excellent thermal stability and high triplet energy, which helps confine excitons and improve device efficiency. It is also employed in multilayer OLED architectures due to its good film-forming properties and ability to block lower-energy excitons. Additionally, it serves as a building block in the design of advanced organic semiconductors for display and lighting technologies.
