Used in organic light-emitting diodes (OLEDs) as a key component in emissive and host materials due to its excellent thermal stability and efficient charge transport properties. Its rigid molecular structure enhances blue light emission, making it valuable in display technologies and solid-state lighting. Commonly employed in phosphorescent and thermally activated delayed fluorescence (TADF) OLED devices to improve device efficiency and longevity. Also utilized in research for developing high-performance optoelectronic materials.
