摘要：

A new highly selective and sensitive chemosensor 1 for both Al3+ and F- was designed and synthesized. 1 could detect both Al3+ and F- with turn-on fluorescence behavior in a nearly perfect aqueous solution. The binding stoichiometry of receptor 1 with Al3+ and F- was proposed to be 1:1, respectively, based on Job plot, H-1 NMR titration and ESI-mass spectrometry analysis. The detection limits (1.12 mu M for Al3+ and 7.01 mu M for F-) of 1 for Al3+ and F- were lower than the World Health Organization guidelines (7.41 mu M for Al-3+ and 79 mu M for F-) for drinking water. Chemosensor 1 was also successfully applied to living cells for simultaneous detection and quantification of both Al3+ and F-. Moreover, the sensing mechanisms of 1 toward Al3+ and F- were explained by theoretical calculations. (C) 2016 Elsevier Ltd. All rights reserved.
