The synthesis and full characterization of new platinum complexes bearing a bulky asymmetric dianionic tridentate ligand is reported. The hindrance of the ligand prevents detrimental intermolecular interactions yielding to highly emitting species in both crystalline state and thin‐film. Such properties prompted their successful use in solution‐processed OLEDs, showing remarkable external quantum efficiency up to 5.6%.
