Water soluble chromone Schiff base derivatives as fluorescence receptor for aluminium(III)

Abstrakt

A novel water-soluble chromone Schiff base derivatives bearing polyhydroxylated moiety were prepared and applied for specific recognition of metal ions in aqueous medium. Their selective fluorescence response to Al(III) over a variety of other biologically important metal ions were demonstrated.

Electronic parameters of the sensors were also studied by quantum chemical computations.
