Used as a host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its high triplet energy level makes it effective at confining excitons, improving device efficiency and reducing energy loss. The compound’s rigid molecular structure contributes to good thermal stability and morphological integrity in thin films, which supports long operational lifetimes in OLED displays and lighting. It is also employed in research settings to develop high-performance emissive layers due to its excellent charge transport properties and compatibility with various dopants.
