Abstract
Two indole-based fluorescent chemosensors 1 and 2 were prepared and investigated characteristic features with transition metal ions. Sensors 1 and 2 were selective for Hg 2+ ion, among a series of metal ions, in aqueous ethanol (H 2O-EtOH, 1:2, v/v) with association constants of 5.74×10 3 and 4.46×10 3 M -1 and detection limits of 7.4 and 6.8 μM, respectively. Computational results revealed that sensor 1 or 2 with Hg 2+ ion formed 1:1 complex with a central, sandwichcoordinated Hg 2+ ion. Computational calculations provided evidence that a sandwich-coordinated Hg 2+ ion center was formed and the polyoxyethylene spacer acted as a scaffold for bringing functional ligands into a suitable geometry.
