Used as a high-performance host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its rigid, twisted molecular structure provides excellent thermal stability and high triplet energy, making it effective at confining excitons and preventing energy back-transfer in blue emitters. The compound helps improve device efficiency, reduce efficiency roll-off, and extend operational lifetime due to its good charge transport properties and morphological stability when used in thin films. It is also employed in multilayer OLED architectures as a key component in the emissive layer.
