Used as a high-performance hole-transporting material in organic light-emitting diodes (OLEDs), enabling efficient electron blocking and improved device stability. Its sterically hindered carbazolyl groups enhance thermal stability and prevent molecular aggregation, making it ideal for blue OLEDs with low efficiency roll-off. Also employed in perovskite solar cells to facilitate efficient hole extraction and boost power conversion efficiency. Suitable for use in thermally activated delayed fluorescence (TADF) devices due to its high triplet energy and excellent morphological stability.
