A series of mononuclear Cu(I)–halide complexes, [CuX(PPh3 )2 (L)] (X=Cl, Br, I; PPh3 =triphenylphosphine; L=pyridine (py), isoquinoline (iq), 1,6-naphthyridine (nap)), were synthesized. The emission color of [CuX(PPh3 )2 (L)] varies from blue to red by changing the L ligands and the halide ions, and all the complexes exhibit high emission quantum yields (0.16–0.99) in the crystals. The emission studies revealed that the emissive states of [CuX(PPh3 )2 (L)] differ depending on the L ligand. Complexes [CuX(PPh3 )2 (py)] and [CuX(PPh3 )2 (nap)] mainly emit from the singlet metal-to-ligand charge transfer mixed with the halide-to-ligand charge transfer (1(M+X)LCT) state at room temperature. In contrast, emissions from [CuX(PPh3 )2 (iq)] at room temperature originate from both 3(M+X)LCT and 3ππ* states. These results indicate that N -heteroaromatic ligands play an important role in the emission properties of mononuclear Cu(I)–halide complexes.
