Abstract
A series of new cyclometalated Ir(III) complexes with thioether groups were synthesized and characterized. One of the crystal structure was determined. The interaction between the complexes and mercury ions was investigated by UV−vis absorption, photoluminescence, 1H NMR and mass spectroscopies. Upon addition of mercury ions to the complexes, the emission intensity of the complexes was significantly quenched due to the new complexes with aldehyde groups formed. These fluorophores have a large linear range (0.5 ~15.0 μM) and low detection limit (40 nM) toward mercury ions. The sensor was sensitive, quick and easy to detect Hg2+, especially it showed a high specificity to mercury ions. It is important for the highly selective recognition of Hg2+ in environment and biological samples.
