Abstract

A simple fluorescent sensor has been developed for the recognition of Fe(III) in semi-aqueous solution at pH 7.0. The sensor, containing two Schiff base type receptors directly connected to naphthalene fluorophores, shows a concentration dependent decrease in emission intensity upon Fe(III) addition. The sensor was selective for Fe(III) over other metal ions and can measure Fe(III) ion concentration between 0.05 and 0.12 mM. The binding stoichiometry was established as 1:1 (host: guest) with a binding constant (Log beta) of 4.01. Furthermore, the addition of Fe(III) to a solution of caused a colour change from light yellow to colourless meaning is also capable of detecting Fe(III) by the naked eye.
