A series of phosphorescent platinum(II) complexes containing various phenyldiazine-type bidentate N^C ligands has been successfully synthesized and characterized. Structural modifications have been made to bidentate cyclometalating ligands regarding the nature of diazine ring (pyrimidine, pyrazine and quinazoline), the substituent groups at the C4 position of the pyrimidine ring (OCH3, CF3) and the EDG groups at the para position of the Pt atom (OCH3, Ph, NPh2, carbazol). In addition, the electronic properties of the azaheterocyclic auxiliary ligand have been modulated in this series of complexes (pyridine, 4-methoxy-pyridine or pyrimidine). X-ray diffraction studies were performed on three complexes, revealing Pt(II) ions in a distorted square-planar geometrical environment with no Pt(II)…Pt(II) interactions but with moderate pi-pi interactions in the solid-state structure. Electrochemical and computational studies suggest a ligand-centered reduction on the diazine ligands with in some cases additional contribution from the azaheterocyclic ancillary ligand, whereas oxidation occurs on the Pt-phenyl ring substituents moiety. All complexes exhibit phosphorescence emission ranging from green to red/near-infrared, both in solution and in the solid state. Complexes bearing a 2-(3-methoxyphenyl)pyrimidine ligand showed the best PLQY of the series, up to 52% in CH2Cl2 solution and 20% in solid state. Furthermore, the solid state PLQY of one of the near-infrared emitting phenylquinazoline complex was found to be 6%.
