【 摘 要 】
5-( N -Ethylcarbazol-3-yl)thiophene-2-carbaldehyde (ECTC), was synthesized by Suzuki coupling reaction and characterized by 1 H NMR, 13 C NMR and elemental analysis. This compound strongly quenches fluorescence of Fe 3+ ion, whereas almost no quenching is observed in the presence of other metal ions including Na + , K + , Mg 2+ , Ca 2+ , Cu 2+ , Mn 2+ and Co 2+ . Under optimized conditions, the fluorescence intensity of ECTC is quenched in a linear fashion by Fe 3+ ion in a wide range of 0.1 μ m –10 μ m with the limit of detection below 0.1 μ m .
