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 electron-donating properties and hole-transport capabilities make it suitable for enhancing device efficiency and lifetime. Also employed in perovskite solar cells as a component in hole-transport layers to improve charge extraction and device performance. Additionally, serves as a building block in the synthesis of larger conjugated systems for optoelectronic applications.
