Used as a key intermediate in organic semiconductors, particularly in the development of blue-emitting materials for OLEDs (organic light-emitting diodes). Its rigid molecular structure enhances thermal stability and improves charge transport, making it suitable for use in electron-transport layers and host materials in display and lighting technologies. Also employed in the synthesis of conjugated polymers and small molecules for optoelectronic devices due to its favorable triplet energy level and hole-transport properties.
