Used as a highly efficient phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in the fabrication of sky-blue and white OLED devices. Its copper-based structure provides strong luminescence with relatively low material cost compared to noble metal complexes like iridium or platinum. Exhibits good thermal stability and film-forming properties, making it suitable for vacuum-deposited OLED layers. Also investigated in optoelectronic applications such as sensors and light-emitting electrochemical cells (LECs) due to its tunable emission and charge-transport characteristics.
