Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting hosts for OLED (organic light-emitting diode) devices. Its rigid, conjugated structure provides high triplet energy and good thermal stability, making it suitable for use in phosphorescent and TADF (thermally activated delayed fluorescence) OLEDs. Commonly employed in display and lighting technologies where efficient hole transport and stable performance are required. Also utilized in the synthesis of advanced hole-transport materials and as a building block in perovskite solar cells for improving device efficiency and stability.
