Used as an electron-transport material in organic light-emitting diodes (OLEDs) due to its high electron affinity and thermal stability. Its branched, multi-aryl structure supports efficient charge transport while inhibiting crystallization, making it suitable for thin-film device applications. Commonly employed in blue-emitting OLED stacks where stable electron injection is critical. Also explored as a host matrix in phosphorescent OLEDs and in perovskite solar cells as an interfacial layer to improve device efficiency and longevity.
