摘要
(Figure Presented) 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 cdA -1, and 4.0 lmW-1. © 2008 Wiley-VCH Verlag GmbH & Co.
