Used as a key intermediate in organic semiconductor materials, particularly in the production of blue-emitting hosts for OLED (organic light-emitting diode) devices. Its rigid, twisted molecular structure helps prevent aggregation and excimer formation, improving color purity and device efficiency. Commonly employed in phosphorescent and thermally activated delayed fluorescence (TADF) OLEDs due to its high triplet energy and good hole-transport properties. Also utilized in the synthesis of stable, high-performance materials for display and lighting technologies.
