Used as a highly efficient electron-transport and host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent devices. Its strong electron-accepting properties and high triplet energy level make it ideal for improving device efficiency and stability. It helps in balancing charge transport, reducing driving voltage, and preventing energy back-transfer from the emitter, which enhances overall luminous performance. Also explored in thermally activated delayed fluorescence (TADF) systems due to its ability to stabilize excited states and support efficient exciton utilization.
