En Route to High External Quantum Efficiency (∼12%), Organic True-Blue-Light-Emitting Diodes Employing Novel Design of Iridium (III) Phosphors

True‐blue Ir(III) phosphors are designed, synthesized, and applied to multilayered organic true‐blue‐light‐emitting diodes with CIEx,y color chromaticity of (0.15,0.11) and maximum external quantum efficiency of ∼12%, demonstrating unprecedented performance among all blue‐phosphorescent OLEDs ever d...

Summary:True‐blue Ir(III) phosphors are designed, synthesized, and applied to multilayered organic true‐blue‐light‐emitting diodes with CIEx,y color chromaticity of (0.15,0.11) and maximum external quantum efficiency of ∼12%, demonstrating unprecedented performance among all blue‐phosphorescent OLEDs ever documented. The molecular‐design strategy and subsequent device‐fabrication protocol reveal a major development in OLEDs.
