title: Efficient "pure" blue OLEDs employing tetradentate Pt complexes with a narrow spectral bandwidth.
abstract: 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.
