Efficient deep‐blue‐emitting tetradentate platinum complexes with a narrow spectral bandwidth are presented, which demonstrate CIEx ≈ 0.15 and CIEy < 0.1. Ultimately, an organic light‐emitting diode (OLED) with 24.8% peak external quantum efficiency and CIE coordinates of (0.147, 0.079) is fabricated using PtON7‐dtb.
