Used primarily as a hole-transport and electron-blocking material in organic light-emitting diodes (OLEDs). It is especially effective in blue-emitting OLED devices due to its high triplet energy level and suitable HOMO-LUMO alignment. The compound enhances device efficiency by preventing exciton quenching and improving charge balance within the emissive layer. It is also employed in multilayer OLED structures as a host material or interlayer to improve operational stability and luminance. Its thermal stability and amorphous nature make it suitable for vacuum-deposited thin films in display and lighting technologies.
