Widely used in organic electronics, this compound serves as a key building block in the synthesis of host materials for blue phosphorescent OLEDs. Its rigid structure and high thermal stability make it ideal for enhancing device efficiency and longevity. It is also employed in the development of organic semiconductors and light-emitting diodes due to its excellent hole-transport properties and ability to suppress aggregation-caused quenching. Additionally, it finds use in research settings for designing thermally activated delayed fluorescence (TADF) emitters.
