Figure 1.

Ligand control strategy toward the development of two‐coordinate Au(I) complexes with low‐energy emissions. Top structures show the chemical structures of the Au(I) complexes with varied amido ligands. Bottom images illustrate the electronic effects exerted by the amido ligands, and comparisons of maximum external quantum efficiencies and peak electroluminescence wavelengths of devices with previous (empty circles) and our (red stars) coinage metal complexes.
