摘要：

A new prototype of multifunctional chemosensor 1 has been synthesized for Fe2+/3+, Cu2+ and CN- in aqueous solution. This sensor could simultaneously detect biologically important metal ions (iron and copper) through colorimetric methods over most other competitive cations. The detection limit (2.9 mu M) of 1 for Cu2+ is lower than WHO guideline (31.5 mu M) in drinking water. Interestingly, the resulting 1-Cu2+ complex sensed cyanide in colorimetric and fluorometric ways, showing recovery from 1-Cu2+ to 1, over other common interference anions. These results demonstrate a novel type of versatile chemosensor for multiple target ions using two different sensing methods, simple colorimetric and sequential detections. (C) 2016 Elsevier B.V.
