Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs), due to its rigid spiro structure and good thermal stability. Its extended π-conjugated system enhances charge transport properties, making it suitable as a host or emitter material in blue-emitting OLED devices. The compound’s high triplet energy level supports efficient energy confinement in phosphorescent and thermally activated delayed fluorescence (TADF) OLEDs. Additionally, its structural rigidity reduces aggregation-caused quenching, improving device efficiency and lifetime. Also explored in organic photovoltaics and as a building block for advanced optoelectronic materials.
