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　1.04×1010　(mol/L)　-2　by　Benesi-Hildebrand　equation.　©　2014　SIOC,　CAS,　Shanghai,　&　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
