A highly sensitive and selective Schiff base fluorescent chemodosimeter for aluminum(III)

Abstract

A fluorescent probe for Al³⁺, 4-(1′-phenyl-3′-methyl-5′-hydroxypyrazole)-1-acetone-(2′-hydroxybenzoyl) hydrazone (L), was prepared through a simple synthetic route. The fluorescent probe can detect Al³⁺ ions sensitively, in ethanol solution with the detection limit of 2.5 × 10⁻⁸ M via photoinduced electron transfer progress. The presence of interfering metal ions and chelators had little influence on the selectivity of Al³⁺. The probe could serve as an excellent chemodosimeter for Al³⁺ in ethanol.
