Halide Ligands

Conventional bottom-emitting devices with three-layered structures containing sublimable three-coordinate copper(i) complexes produce bright green luminescence with maximum external quantum efficiencies (EQE) of 18.6–22.5%.

Red Oleds

In comparison with green and red OLEDs, which have well developed with satisfactory electroluminescence (EL) performances, high-efficiency blue OLEDs still need further exploration. Herein, by reasonably strengthening the rigidity of...
