Used as a host material in organic light-emitting diodes (OLEDs), particularly in blue-emitting layers due to its high triplet energy and good thermal stability. Its purified form ensures minimal quenching sites, enhancing device efficiency and lifetime. Commonly employed in evaporated OLEDs where sublimation-grade purity is critical for uniform thin-film deposition. Also suitable for use in organic semiconductors and optoelectronic devices requiring high charge carrier mobility and morphological stability.
