Used as a hole-transporting material in organic light-emitting diodes (OLEDs), enhancing device efficiency by improving charge injection and transport. Also applied in organic photovoltaics (OPVs) as a donor material due to its strong light absorption and favorable energy levels. Shows potential in electrochromic devices and sensors owing to its reversible redox behavior and intense fluorescence. Its thermal stability and film-forming properties make it suitable for thin-film applications in optoelectronic devices.
