A series of tetradentate Pt(II) emitters containing fused 5/6/6 metallocycles have been designed and synthesized. Mol. geometries play a critical role in determining the photophys. properties. Their emission spectra are significantly affected by the geometries of the mol. core skeletons, the substituents, even hydrogen atoms, and their positions, which are further supported by X-ray crystallog. analyses and theor. calculations The generation of excimer emissions is observed in the tetradentate 5/6/6 Pt(II) emitters for the first time and found to be concentration-dependent both in the solution and solid states. All of the Pt(II) emitters have high photoluminescent quantum efficiency of up to 100% and luminescent lifetime as short as 1.4 μs at room temperature, achieving a radiative rate of 7.14 × 105 s-1. Their emission color can be easily tuned to cover the whole visible region (λmax = 464-632 nm) through selective synthetic modification of the heteroaromatic rings of the ligands. Pt(1-ptz)-based sky blue organic light-emitting diode (OLED) demonstrates a maximum external quantum efficiency (EQE) of 14.5%, yet maintains an EQE of 12.7% at a high brightness of 1000 cd/m2. This work demonstrates that these tetradentate Pt(II) complexes can act as efficient phosphorescent emitters for OLED applications.
