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

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.
