Highly Efficient Blue-Emitting Iridium(III) Carbene Complexes and Phosphorescent OLEDs

Bright & blue: A strategy for reducing metal‐chelate internal strain enables the preparation of blue emitting iridium(III) carbene complexes (see picture; Ir red, N light blue, F green). The phosphorescent OLED fabricated from one of these complexes shows remarkable CIE coordinates of (0.16, 0.1...

Zusammenfassung:Bright & blue: A strategy for reducing metal‐chelate internal strain enables the preparation of blue emitting iridium(III) carbene complexes (see picture; Ir red, N light blue, F green). The phosphorescent OLED fabricated from one of these complexes shows remarkable CIE coordinates of (0.16, 0.13) and peak efficiencies of 6.0 % photons per electron, 6.3 cd A−1, and 4.0 lm W−1.
