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, conjugated structure enhances thermal stability and improves charge transport properties, making it suitable for high-performance optoelectronic applications. Also employed in host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it serves as a building block in the synthesis of advanced functional polymers and small molecules for photovoltaic cells and field-effect transistors.
