Used primarily in organic light-emitting diodes (OLEDs) as a host material in blue-emitting layers due to its high triplet energy and good hole-transport properties. It is especially effective in phosphorescent OLEDs where it helps confine excitons on the emitter, improving device efficiency. Its rigid molecular structure contributes to high thermal stability, making it suitable for use in high-performance, long-lasting display and lighting technologies. Also employed in research settings for developing new organic semiconductors and optoelectronic devices.
