Used as a high-performance hole-transporting material in organic light-emitting diodes (OLEDs), enabling efficient blue emission with low driving voltage. Its rigid molecular structure provides excellent thermal stability and prevents crystallization in thin films, making it ideal for long-lasting display and lighting devices. Also employed in perovskite solar cells to improve device efficiency and stability by facilitating effective charge extraction. Its deep HOMO level allows for good energy level matching with various emissive layers, enhancing overall device performance.
