Widely used in organic electronics, this compound serves as a key hole-transport material in organic light-emitting diodes (OLEDs). It helps improve device efficiency by facilitating the movement of positive charges from the anode to the emissive layer. Its stable aromatic structure and good film-forming properties make it suitable for use in display technologies and solid-state lighting. Additionally, it is employed in perovskite solar cells for enhancing charge extraction and device performance. The compound’s high glass transition temperature contributes to thermal stability, which is critical for long-term operation of optoelectronic devices.
