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.
