A novel multifunctional chemosensor HL bearing a julolidine unit and a Schiff base unit has been synthesized. As a fluorescent sensor, HL exhibited excellent selectivity and high sensitivity to Al3+ and F-/CN- with a low detection limit in acetonitrile. Moreover, HL also showed good colorimetric selectivity to F-/CN-; a solution color change from colorless to light yellow in acetonitrile was observed by the naked-eye'. The properties of HL with Al3+ and F-/CN- were studied by UV-vis absorption spectroscopy, fluorescence spectroscopy, high-resolution mass spectrometry and H-1 NMR titration. Furthermore, the cell imaging experimental results indicated that the chemosensor HL could be applied for the detection of Al3+ in living cells.
