Used as a high-performance organic semiconductor material in optoelectronic devices such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its extended π-conjugated structure enables efficient charge carrier transport and excellent thermal stability, making it suitable for thin-film electronics. Also employed in perovskite solar cells as a hole-transporting layer due to its favorable energy level alignment and film-forming properties. Additionally, finds use in fluorescent sensors and electrochromic devices owing to its tunable electronic properties and reversible redox behavior.
