•Two iridium complexes have been synthesized.•The two complexes vary by their respective cyclometalated ligands.•UV–vis absorption and photoluminescence spectroscopy of complexes are investigated.•The substitution pattern determined the electroluminescence performances.
Two heteroleptic iridium complexes were synthesized and their photophysical properties studied. The two complexes vary by their ancillary ligand that is respectively acetylacetone (acac) or dibenzoylmethane (dbm). Interestingly, only the acac-based complex proved to be highly emissive and electroluminescent devices were only fabricated with this complex. In order to determine the emissive properties of this new complex, comparison with complexes previously reported in the literature was established.
