Highly luminescent Cu I complexes with one phenanthroline and one (bis[2‐(diphenylphosphino)phenyl]ether) ligand show an emission quantum yield of up to 28 % upon deactivation of the metal‐to‐ligand charge‐transfer excited states; their X‐ray crystal structure shows a distorted tetrahedral geometry (see figure and inside cover). One of these compounds is used as an active material in a light‐emitting electrochemical cell; it exhibits an efficiency similar to that of Ru II ‐type complexes.
