Used as a key intermediate in organic semiconductor materials, particularly in the production of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid carbazole core and extended aromatic structure enhance hole transport properties and improve thermal stability in optoelectronic applications. Also employed in the synthesis of host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it serves as a building block in the development of photorefractive materials and organic photovoltaics.
