The synthesis of the first examples of phosphorescent binuclear cyclometalated N‐heterocyclic carbene C^C* μ‐pyrazolate platinum(II) complexes are reported and the photophysical characterization of the single isomers is described. The complexes exhibit a strong phosphorescent emission in the blue region of the visible spectrum with very high quantum yields of up to 86 % at room temperature (PMMA film) and 98 % at 77 K (2‐MeTHF).
