| Abstract: The probe 1 was readily prepared via condensation of 8-formyl-7-hydroxy-coumarin and carbonic dihydrazide in a one-step procedure. Probe 1 exhibited high sensitivity and selectivity towards Zn2+ and F- through a "turn-on" fluorescence response and/or ratiometric colorimetric response with low detection limits of the order of 10-8 mol·L-1. The complex behaviour was fully investigated by spectral titration, isothermal titration calorimetry, 1H NMR spectroscopic titration and mass spectrometry. Interestingly, probe 1 not only recognizes the cation Zn2+ and the anion F-, but can also distinguish between these two ions via the max wavelength in their UV-Vis spectra (360 nm for 1-Zn2+ vs 400 nm for 1-F- complex) or their fluorescent spectra (λex, λem=360, 454 nm for 1-Zn2+ vs λex, λem=400, 475 nm for 1-F- complex) due to their differing red-shifts. Additionally, probe 1 has been further explored in the detection of Zn2+ in living cells. |
