Abstract

A series of indole-based fluorescent chemosensors 1-4 were prepared and investigated characteristick features with transition metal ions. Sensors 1 and 2 were selective for Hg²⁺ ion among a series of metal ions in H ₂O-DMSO with association constants of 4.60×10⁴ and 5.90×10⁴ M^-1 and detection limits of 140 and 101.6 μM, respectively.
