Used as a host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent devices. Its high triplet energy level makes it effective at confining excitons, improving device efficiency. It also serves as a matrix for emissive layers due to its good thermal stability and ability to form uniform amorphous films. Additionally, it functions as a ligand or building block in metal-organic complexes for catalysis and luminescent materials.
