In this paper, we report the synthesis, characterization and Fe3+-sensing properties of a series of new artificial fluorescent molecular clips, and structure of clip 1 is confirmed by X-ray crystallography. All these molecular clips had the ability to bind and sense Fe3+selectively through decrease fluorescence responses in THF-MeOH-Water. Fluorimetric titration experiment indicated that the quenching of these compounds' fluorescence upon Fe3+probably arises from the electron/energy transfer between Fe3+and the excited chemosensors. The limit of detection, linear concentration range and selectivity of the fluorescent molecular clips were evaluated in this study as well.
