Abstract:

We have demonstrated a turn-on fluorescent sensor 6 for detection of Fe3+ based on photo-induced electron transfer (PET) mechanism. The probe comprises a perylene tetracarboxylic diimide (PDI) fluorophore and two bis((1,2,3-triazol-4-yl)methyl)amine (DTA) moieties as the metal ion receptors. It exhibits high selectivity toward Fe3+ over various other metal ions in CH3CN/H2O (1:1, V/V). The binding stoichiometry for 6-Fe3+ complexes has been determined to be 1:2 by a Job plot of fluorescence. The association constant between 6 and Fe3+ was estimated to be 1.04x10(10) (mol/L)(-2) by Benesi-Hildebrand equation.
