Two novel dibenzothiophene-S,S-dioxide-based iridium complexes with yellow emission were fully synthesized and characterized. The photophysical, electrochemical and thermal properties, as well as electroluminescent properties of the resulting iridium complexes were discussed. Both the iridium complexes possess good thermal stability and high photoluminescence quantum yields. Also, we have successfully fabricated singly doped emissive layer (SDEL) hybrid white organic light-emitting devices (WOLEDs) using (3-PyFSO)2IrPic or (2-PyFSO)2IrPic as yellow-emitting phosphors and 4,4′,4″-tris(N-carbazolyl)triphenylamine (TCTA) as host and blue-emitting fluorophor. The WOLEDs with (3-PyFSO)2IrPic show a maximal power efficiency (PE) of 4.28 lm/W at a brightness of 3.7 cd/m2and a Commission Internationale de L'Eclairage (CIE) coordinates of (0.227, 0.260). Compared to (3-PyFSO)2IrPic, the WOLEDs based on (2-PyFSO)2IrPic exhibit a little better device's performances with a maximum PE of 4.70 lm/W at a brightness of 2.6 cd/m2and a CIE coordinates of (0.244, 0.243).
