Used as a high-performance organic semiconductor in OLED (organic light-emitting diode) devices, particularly as a host material in blue phosphorescent OLEDs. Its rigid, planar structure provides excellent thermal stability and efficient charge transport, enhancing device efficiency and lifetime. Also employed in organic photovoltaics and field-effect transistors due to its strong π-conjugation and favorable energy level alignment. Suitable for use in display technologies and solid-state lighting where high brightness and energy efficiency are required.
