| Abstract: | The synthesis, excited‐state dynamics, and applications of two series of air‐stable luminescent tungsten(VI) complexes are described. These tungsten(VI) complexes show phosphorescence in the solid state and in solutions with emission quantum yields up to 22 % in thin film (5 % in mCP) at room temperature. Complex 2 c , containing a 5,7‐diphenyl‐8‐hydroxyquinolinate ligand, displays prompt fluorescence (blue–green) and phosphorescence (red) of comparable intensity, which could be used for ratiometric luminescent sensing. Solution‐processed organic light‐emitting diodes (OLEDs) based on 1 d showed a stable yellow emission with an external quantum efficiency (EQE) and luminance up to 4.79 % and 1400 cd m−2 respectively. These tungsten(VI) complexes were also applied in light‐induced aerobic oxidation reactions. |
