Abstract: The development of a europium(III) based probe (EuL1) for the detection of Cu(II) ions and hydrogen sulphide is presented. With the addition of Cu(II) ions, EuL1 displayed the greatest quenching among the other cations examined. The binding constant was 74 026 +/- 2899 M-1. Once combined with Cu(II) ions, EuL1Cu demonstrated high specificity for hydrogen sulfide compared to other organic and inorganic sulfur compounds. EuL1Cu exhibited an on-off-on type luminescence change with the alternate addition of Cu(II) ions and H2S along with reversible forming-separating of the complex.
