Used as a high-performance organic semiconductor in optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid, star-shaped aromatic structure provides excellent thermal stability and efficient π-π stacking, enhancing charge transport properties. Commonly employed as a host material in emissive layers of OLEDs, especially for blue phosphorescent devices, due to its high triplet energy level and ability to prevent exciton quenching. Also utilized in organic field-effect transistors (OFETs) as an electron-transport layer for improved device efficiency and stability.
