In this contribution, a new fluorescent probe is presented which is capable of the selective recognition and determination of dodine (DD) from amongst 14 different pesticides. The system utilizes a simple guest-replacement mechanism, which allows for fluorescence turn-on. The probe is constructed from cucurbit[10]uril (Q[10]) and protonated acridine (MeAD), and makes use of the strong fluorescence ability of MeAD in aqueous solution versus the lack of fluorescence for the homoternary inclusion complex MeAD2@Q[10]. The addition of pesticide DD to an aqueous solution of MeAD2@Q[10] resulted in MeAD displacement and subsequent recovery of the strong fluorescence. Interestingly, the similar addition of a number of other common pesticides (13 others were tested herein) failed to result in the recovery of the fluorescence. 1H NMR spectroscopic studies were employed to investigate the guest-replacement fluorescence turn-on mechanism.
