Used as a host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent devices due to its high triplet energy level. Its structure supports efficient energy transfer and helps prevent exciton quenching, improving device efficiency and stability. Also employed in thermally activated delayed fluorescence (TADF) OLEDs as a donor or host component. Shows promise in enhancing electron transport and device longevity in emissive layers.
