Used primarily as a hole-transport material in organic light-emitting diodes (OLEDs). Its molecular structure supports efficient charge transport and enhances device stability. Commonly applied in display technologies and solid-state lighting due to its ability to form stable amorphous films and high glass transition temperature. Also employed in multilayer OLED architectures to improve electron-hole balance, leading to higher luminous efficiency. Shows promise in flexible electronics because of its thermal and morphological stability.
