A new fluorescent and colorimetric chemosensor for Al³⁺ and F^-/CN^- based on a julolidine unit and its bioimaging in living cells.

ABSTRACT: 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 ¹H NMR titration. Furthermore, the cell imaging experimental results indicated that the chemosensor HL could be applied fo
