Used as a key intermediate in organic light-emitting diodes (OLEDs), particularly in blue-emitting layers due to its high triplet energy and good thermal stability. Its structure supports efficient hole transport and enhances device efficiency in phosphorescent and thermally activated delayed fluorescence (TADF) OLEDs. Commonly employed in display and lighting technologies where stable and efficient blue emission is critical. Also utilized in host materials to prevent exciton quenching and improve operational lifetime of devices.
