Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid molecular structure enhances thermal stability and improves charge transport properties, making it suitable for high-performance optoelectronic applications. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy level, which helps prevent back-energy transfer and improves device efficiency. Also utilized in the synthesis of hole-transporting materials and as a building block in perovskite solar cells to enhance device stability and performance.
