Used as an electron-transporting and host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent devices. Its rigid, twisted molecular structure helps suppress aggregation and excimer formation, improving color purity and device efficiency. Exhibits high triplet energy, enabling effective energy confinement for blue emitters. Also employed in thermally activated delayed fluorescence (TADF) OLEDs due to good stability and film-forming properties when deposited via vacuum evaporation. Suitable for use in multilayer OLED architectures where balanced charge transport is required.
