Used as a photostabilizer in organic light-emitting diodes (OLEDs), particularly in blue-emitting devices. It helps improve device efficiency and operational lifetime by reducing degradation caused by light and heat exposure. Its strong electron-accepting nature makes it suitable as an electron-transport material in multilayer OLED architectures. Also employed in perovskite solar cells as an interfacial layer to enhance charge extraction and device stability. Shows promise in optoelectronic applications where thermal and photochemical stability are critical.
