    • 3, as for other quinoline-based fluorescent chemosensors reported in the literature, is taken at the maximum of the lowest energy absorption band whose absorbance very slightly changes on adding metal ions (see refs 38, 56, 59, 62-66). We have verified that when exdting at the isosbestic wavelengths, the fluorescence intensity emission observed in the presence of metal ions is much lower or approaches zero depending on the closeness of the isosbestic point to the lowest energy absorption band of the ligands. However, for all the spectrofluorimetric titrations described in the paper, emission data were corrected for the absorbed light when necessary (see Experimental Section)
