Used as a hole-transporting material in organic light-emitting diodes (OLEDs) and perovskite solar cells due to its excellent charge transport properties and stability. Its electron-rich structure enhances device efficiency by facilitating effective hole injection and reducing energy barriers. Also employed in photoconductive layers of imaging devices and as a building block in organic semiconductors for flexible electronics. Shows potential in electrochromic devices and sensors owing to its reversible redox behavior and strong amorphous film-forming ability.
