Used in organic light-emitting diodes (OLEDs) as an efficient host or emitting material due to its strong blue fluorescence and high thermal stability. Its rigid molecular structure supports good charge transport properties, making it suitable for use in blue-emitting layers of OLED displays and lighting devices. Also explored in optoelectronic applications such as organic photovoltaics and organic field-effect transistors (OFETs) where stable and efficient hole transport is required.
