Two new isomerous PET fluorescent chemosensors (L and L') for Al 3+ have been designed, synthesized and characterized. The two chemosensors exhibited fluorescence enhancement upon binding Al3+ in CH3-CN by PET inhibition processes from both the sulfur and the nitrogen donors to anthracene. The job's plot, Benesi-Hildebrand plot and 1H NMR titration experiments indicate that both chemosensors form a 1: 1 complex with Al3+. The binding constants were calculated to be (1.432 ±0.186) × 105 and (1.427 ± 0.970) × 105, respectively. Furthermore, the lowest detection limit for Al3+ in CH3CN was determined to be 4.8 × 10 7 M and 2.2 × 10 7 M, respectively.

A method for the synthesis of substituted phthalic anhydrides (IV) wherein R' is a halogen, aromatic or aliphatic group comprising 1-18 carbons, hydrogen or nitro group is the transimidation between a substituted N-alkyl phthalimide (V) wherein R is an alkyl having from 1 to 18 carbons, and a substituted tetrahydrophthalic anhydride (VI): The by product of this reaction, a substituted N-alkyl tetrahydrophthalimide (VII), may be converted by aromatization to the substituted N-alkyl phthalimide (V).
