Used in organic light-emitting diodes (OLEDs) as an efficient blue emitter or host material in the emissive layer. Its rigid, conjugated structure provides high thermal stability and good charge transport properties, making it suitable for high-performance, long-lasting OLED displays and lighting devices. Commonly employed in the fabrication of deep blue devices due to its ability to maintain color purity and efficiency. Also explored in phosphorescent and thermally activated delayed fluorescence (TADF) systems as a host for dopants, enhancing device efficiency and reducing energy loss.
