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 rigid, twisted molecular structure provides excellent thermal stability and high triplet energy, which helps confine excitons and improve device efficiency. It is also employed in organic photovoltaics and perovskite solar cells as a hole-transporting layer due to its suitable energy levels and good film-forming properties. Its deep HOMO level enables effective hole injection and enhances operational stability in optoelectronic applications.
