 We developed new cationic tricoordinated copper complexes bearing an NHC and a bidentate pyridine-based ligand [Cu(NHC)(N^N)][X] which exhibit luminescence in solid state.^[1],[2] Varying the electronic properties of both NHC and N^N ligands, we established some structure – properties relationships, supported by structural, photophysical and TD-DFT studies. We demonstrated that the luminescence of these copper complexes was a combination of Thermally Activated Delayed Fluorescence (TADF) and phosphorescence. Thanks to the high quantum yields of some complexes, their application in Light emitting Electrochemical Cells (LECs) was considered. We report in this presentation, to the best of our knowledge, the first blue LECs devices incorporating copper complexes.²
