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, which enhances thermal stability in thin films. Commonly employed in blue OLEDs, it facilitates balanced charge injection and reduces exciton quenching. Also utilized in perovskite solar cells as a dopant-free hole-transport layer, contributing to long-term performance and lower manufacturing costs. Its good film-forming properties make it suitable for vacuum-deposited and solution-processed optoelectronic devices.
