Used as an organic semiconductor material in optoelectronic devices, particularly in organic light-emitting diodes (OLEDs) and organic thin-film transistors (OTFTs). Its extended aromatic structure provides good charge carrier mobility and thermal stability, making it suitable for use in display technologies and flexible electronics. Often employed as a hole-transport layer due to its favorable energy levels and ability to form stable amorphous films. Also investigated in perovskite solar cells as a dopant-free hole-transport material to improve device efficiency and longevity.
