A highly sensitive and selective optical chemosensor (Arg-Rhoen) for determination of Au3+ was prepared by covalent immobilization of rhodamine ethylenediamine on agarose gel. Spectrophotometric studies of complex formation, chem. structures and purity of the hydrogel sensor were carried out using TGA, NMR, TEM, and IR. The complexation study results indicated that this probe can selectively detect Au3+ via a metal ion chelation-induced ring-opening reaction, and then caused a remarkable color change from colorless to pink and a strong fluorescence enhancement. Theor. DFT calculation results suggested that the hydrogel sensor formed stable complexes with Au3+ through a large number of cation-dipole interactions. Reusability has been established by repeatedly dipping and rinsing the hydrogel in aqueous Au3+ and EDTA in basic solutions We believe that this approach may provide an easily measurable and inherently sensitive method for Au3+ detection in environmental and biol. applications.
