Used as a hole-transporting material in organic light-emitting diodes (OLEDs), this compound helps improve device efficiency and stability. Its rigid molecular structure supports high glass transition temperature, reducing crystallization in thin films. It is especially effective in blue OLEDs, where it minimizes energy loss and enhances color purity. Also employed in perovskite solar cells to facilitate charge extraction and increase power conversion efficiency. Its good film-forming properties make it suitable for use in vapor-deposited multilayer devices.
