Abstract: <span style="mso-bidi-font-size:9.0pt;letter-spacing: -.1pt" lang="EN-GB">New iridium(III) complexes, viz., (OctOXD)<sub>2</sub>Ir(tta) and (OctOXD)<sub>2</sub>Ir(tmd) [OctOXD = 2-(4-butyloxyphenyl)-5-phenyl-[1,3,4]oxadiazolato-N4,C2, tta = 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione, tmd = 2,2,6,6-tetramethylheptane-3,5-dione] have been synthesized and characterized. These complexes have two cyclometalated ligands (C^N) and a bidentate diketone ligand {[(C^N)<sub>2</sub>Ir(X)], where X is a β-diketone with trifloromethyl, theonyl or <i style="mso-bidi-font-style:normal">t</i>-butyl groups} and show good thermal stability in air up to 400 <sup>o</sup>C. The photoluminescence spectra of the two complexes show peak emissions at 537 and 557 nm, respectively. The electroluminescent properties of these complexes have been studied by fabricating multilayer devices. The electroluminescence spectra also show peak emission at 541 and 564 nm for (OctOXD)<sub>2</sub>Ir(tta) and (OctOXD)<sub>2</sub>Ir(tmd), respectively. </span>
