Have a look to Ginevra’s and Luca’s last contribution “Design Rule Hidden from The Eye in S/N-Bridged Ancillary Ligands for Copper(I) Complexes Applied to Light-Emitting Electrochemical Cells” on Advanced Functional Materials. Hidden parameters to take in account for the ligand design of Cu(I) complexes applied to highly-performing LECs have been discovered. Find how:  http://doi.org/10.1002/adfm.202304668
