Used as a high-performance host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its strong triplet energy and good hole-transport properties make it effective in enhancing device efficiency and stability. It is valued in display and lighting technologies for enabling high-energy blue emission with reduced efficiency roll-off. Also employed in multilayer OLED architectures due to its suitable energy level alignment and film-forming characteristics.
