A new fluorescent sensor (L) based on imine group including oxygen has been investigated in this work. Chemosensor (L) exhibited highly selective and sensitive fluorescence sensing ability for Fe3+ over other metal ions in a mix of H2O-DMF solution. The new fluorescence quenching response of (L) for Fe3+ indicated that (L) can be used as ‘‘turn-off’’ fluorescent chemosensor to selectively detect Fe3+. The fluorescent sensor (L) was synthesized by the template condensation of salicylaldehyde and a new tetraamine 1:2 molar ratio and characterized by IR, NMR spectroscopy and elemental analysis.
