Used primarily in organic electronics, this compound serves as a hole-transport material in OLED (organic light-emitting diode) devices due to its high triplet energy and excellent thermal stability. Its structural design with bulky fluorenyl groups reduces intermolecular interactions, minimizing exciton quenching and enhancing device efficiency. It is also employed as a host material in phosphorescent OLEDs, particularly for blue emitters, where energy level alignment and stability are critical. Additionally, it finds use in perovskite solar cells as a component in the hole-transport layer, contributing to improved device performance and longevity.
