摘要：

A benzothiazole conjugated quinoline derivative appended with rhodamine-6G acts as an efficient FRET-based single molecular switch for Fe3+. The structure of the probe was confirmed through its single crystal X-ray study. The sensor demonstrates an immediate fluorescence ratiometric response specific towards Fe3+ which also allows facile naked-eye detection of Fe3+. The probe is highly selective only towards Fe3+ in comparison to other environmentally important cations, including Fe2+. Moreover, the detection limit was found to be in the 10(-8) M range for the recognition of Fe3+.
