Used in organic light-emitting diodes (OLEDs) as a host material in blue phosphorescent devices due to its high triplet energy and good thermal stability. Its hole-transport properties make it suitable for enhancing device efficiency and longevity. Also employed in perovskite solar cells as a hole-transporting material to improve power conversion efficiency. Additionally, it serves as a key intermediate for synthesizing more complex carbazole derivatives used in advanced optoelectronic research. Commonly found in optoelectronic applications where stable and efficient charge transport is required.
