Bright & blue: A strategy for reducing metal-chelate internal strain enables the preparation of blue emitting iridium(III) carbene complexes. 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 Im W-1.
