A white OLED with a maximum EQE of 20.1%, CIE coordinates of (0.33, 0.33) and CRI of 80 is fabricated based on platinum(II) bis(N‐methyl‐imidazolyl)benzene chloride (Pt–16). The device emission spectrum and the chemical structure of Pt–16 are shown in the inset of the efficiency versus luminance graph.
