Fluorescence detection of Al(III) using derivatives of oxazoline and imidazoline

The reactivity of Al(III) towards 2-(4,5-dihydro-1,3-oxazol-2-yl)phenol and 2-(4,5-dihydro-1,3-imidazol-2-yl)phenol is reported. The coordination ability, the stoichiometry, and the stability of the adducts formed in solution were studied by UV–Vis spectroscopy and by fluorescence. The efficiency of...

Summary:The reactivity of Al(III) towards 2-(4,5-dihydro-1,3-oxazol-2-yl)phenol and 2-(4,5-dihydro-1,3-imidazol-2-yl)phenol is reported. The coordination ability, the stoichiometry, and the stability of the adducts formed in solution were studied by UV–Vis spectroscopy and by fluorescence. The efficiency of selectively detecting Al(III) for the two molecules is presented. Coordination ability of Al(III) towards 2-(4,5-dihydro-1,3-oxazol-2-yl)phenol ( 1) and 2-(4,5-dihydro-1,3-imidazol-2-yl)phenol ( 2) was studied added to the determination of the stoichiometry of the adducts formed in solution. The fluorogenic sensor character, that means efficiency and selectivity, of the two studied molecules was then quantified.
