Synthesis and characterization of green-to-yellow emissive Ir(III) complexes of pyridylbenzothiadiazine ligand
Abstract
Reaction of Tetrakis(2-phenylpyridinato-<i>C<sup>2</sup></i>,<i>N'</i>)(μ-dichloro)di-iridium with 3-(pyridin-2-yl)-4<i>H</i>-benzo[<i>e</i>][1,2,4]thiadiazine (<b>L1</b>) under neutral and basic media afforded the charged and neutral Ir-complexes, <b>1</b> and <b>2</b>, respectively, in good yields (63 – 79%). Single crystal XRD analysis confirms that the ancillary ligands in both <b>1</b> and <b>2</b> binds to the iridium via coordination of N2 of the benzo[<i>e</i>][1,2,4]thiadiazine. Upon isolation of the neutral complex, the sulfur atom rapidly oxidizes to form <b>2</b>. The UV-vis absorption spectra of the complexes exhibit both ligand-centered and mixed metal-to-ligand and ligand-to-ligand charged transfer (CT) transitions that are typical of many heteroleptic iridium complexes. Complexes <b>1</b> and <b>2</b> were found to be emissive at room temperature in the green and yellow region of the electromagnetic spectrum, respectively, albeit with poor photoluminescence quantum yield (ΦPL = 1.1 – 2.5%).
