A thiocyanate-bridging dimeric cyclometalated iridium(III) complex: Synthesis, structure and phosphorescence behaviours towards metal ions

Electrophosphorescence of a Thiocyanate-Bridging Dimeric Cyclometalated Iridium(III) Complex

“…In our previous research [21] , methyl ester group was introduced into phenylquinoline ligands of iridium complex in order to tune the emission wavelength to saturated red emission, and the phosphorescence behaviours of a neutral dimeric cyclometalated iridium complex, [{Ir(μ-SCN)(pqcm) 2 } 2 ] (Figure 2), towards different solvents and metal ions were investigated and the strong phosphorescence quenching by acetonitrile and two equivalents of Hg 2+ , Cu 2+ and Ag + ions was observed. This research had suggested that the new complex had a red light emitting (638 nm) with a short lifetime of 0.11μs.…”

Syntheses, crystal structures and properties of complexes with two anthracene-based bulky backbone ligands

“…By contrast, anthracenebased bulky backbone ligands, such as phenylquinoline- [17,18] and anthraquinone-based carboxylic acids [19,20], have not yet been widely studied. Therefore, we have selected two anthracene-based bulky backbone ligands, 9,10-dioxo-9,10-dihydroanthracene-1,5-dicarboxylic acid (H 2 L 1 ) and 2-phenylquinoline-4-carboxylic acid (HL 2 ) (Fig.…”

A Novel Charged Iridium (III) Complex for Amine Sensor Application

“…When the ancillary ligand of an iridium(III) complex contains a specific component to interact with the analyte, the presence of this analyte leading to dramatic changes in the photophysical properties of the iridium(III) complex. The ester functional group, in particular, has been frequently used with pyridine or bipyridine (bpy) ligands for metal ion and anion sensors [3,8]. Herein, we report a new charged iridium(III) complex containing ester moiety.…”
