Wide-range color tuning of Iridium Biscarbene complexes from blue to red by different N ∧ N ligands: An alternative route for adjusting the emission colors

Abstract

Organic light-emitting diodes (OLEDs) have attracted a great attention due to their application in high-resolution, full-color, flat-panel displays and lighting sources. [1-6] The search for highly efficient three primary color (red, green, and blue) emitters is an important subject for OLEDs. [7] Phosphorescence devices have continued to attract intense interest because their intrinsic efficiencies could be four times as high as the fluorescence ones.
