Two new ferrocene-pyrene dyads (1and2)bearing amide and thiourea donors were designed and prepared for anion recognition. The structure of1was also characterized by X-ray single crystal analysis. The anion recognition ability of1and2was fully investigated by elecotrochemical and fluorescent techniques. In CH3CN solution, both1and2showed a good electrochemical sensing toward F−, AcO−and H2PO4−, with the ferrocene-based redox potential showing a large negative shift. Interestingly, both1and2exhibited an exclusive fluorescence sensing of F−over other anions, with the fluorescence of the receptors showing a turn-off response. Further, the binding mechanism between receptors and anions was confirmed by1H NMR titrations, which reveal that the two thiourea NH donors, cooperative with the amide donor, play a key role for binding the anions.
