Used in organic electronics, particularly as a building block in organic light-emitting diodes (OLEDs). Its rigid, planar structure enhances charge transport and improves device efficiency. Commonly employed in blue-emitting layers due to its high triplet energy and thermal stability. Also explored in host materials for phosphorescent OLEDs and as a core structure in hole-transport materials. Its extended π-conjugation supports tunable emission properties for use in displays and lighting applications.
