N2 - Abstract: A new and simple colorimetric receptor 1, based on the combination of 2-amino-4-methylphenol moiety and julolidine moiety, has been designed and synthesized. 1 showed a selective colorimetric sensing ability toward F− ion by changing color from yellow to orange, and could be utilized to monitor F− without any inhibition by competitive anions such as CH3COO− and CN−. Based on Job plot, ESI-mass spectrometry and the 1H NMR titration, the binding mode of 1 for F− was proposed to be 1:1. Moreover, the sensing mechanism for F− was theoretically supported by DFT and TD-DFT calculations. Graphical Abstract: [Figure not available: see fulltext.]
