@article { , title = {Detection of the pesticide dodine using a cucurbit[10]uril-based fluorescent probe}, abstract = {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.}, doi = {10.1016/j.microc.2021.106309}, issn = {0026-265X}, journal = {Microchemical Journal}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/3760777}, volume = {167}, keyword = {Specialist Research - Other, Analytical Chemistry, Spectroscopy}, year = {2021}, author = {Lian, Chengjie and Xu, Weitao and Luo, Yang and Zhu, Xinyi and Fan, Ying and Redshaw, Carl and Tao, Zhu and Xiao, Xin} }
