Modulations of various neutral phosphine containing copper(i) complexes exhibiting phosphorescence and TADF are easily achieved by solvent modification restricting intramolecular rotation or by modifying the L-X phosphine-sulfonate chelate. This concept is not limited to solvents as the addition of metallic salts also led to the formation of original well-defined photoluminescent K2CuLX3 and KCuL2X2 cuprate complexes.
