摘要
A new neutral iridium (III) complex Ir(TBT) 2(acac) based on 2-thiophen-2-yl-benzothiazole (TBTH) ligands has been synthesized and characterized. Ir(TBT) 2(acac) exhibited color change from red to orange without and with Hg 2+, at the same time has a blue shift about 23 nm in fluorescent emission spectra. So it can serve as a highly selective chemodosimeter for Hg 2+ with ratiometric and naked-eye detection. The sensor allowed determination of Hg 2+ in the working range of 3 μM-10 μM with a detection limit of 2.14 μM. The phosphorescent chemosensor exhibited excellent selectivity and sensitivity for Hg 2+ detection.
