Abstract

A naphthalene pyridine Schiff base 1 as a fluorescent chemosensor was developed for the detection of Fe2+ ions in CH3CN–H2O solution. Its binding properties toward various other heavy and transition metal ions including Fe3+ ions were examined. The sensor showed high selectivity and sensitivity towards Fe2+ ions in aqueous media with the lower detection limit of 1.5 × 10−7 M. The fluorescence “turn-on” recognition process follows the ICT process and Cdouble bond; length as m-dashN isomerisation. In addition, determination of Fe2+ in a variety of samples were analyzed which includes commercially available tablets, tomato juice, dark chocolate and tap water.
