Tune the colors! Thanks to their excellent photophysical and electrochemical properties, cationic phenylpyridine cyclometalated iridium complexes, containing a triazole–pyridine ligand, generate intense green electrochemiluminescence (ECL) in organic solvents and in water. Fluorination of the ligand allows for the easy and effective modulation of emission to blue (see graphic).
