Used as a high-performance hole-transporting material in organic light-emitting diodes (OLEDs). Its unique molecular structure enables excellent thermal stability and efficient charge transport, making it ideal for blue phosphorescent and thermally activated delayed fluorescence (TADF) OLED devices. Commonly employed in the emissive layer or as a host material to improve device efficiency and operational lifetime. Also explored in perovskite solar cells for its ability to facilitate hole extraction and reduce recombination losses.
