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 H2O–DMSO with association constants of 4.60×104 and 5.90×104?M?1 and detection limits of 140 and 101.6 μM, respectively.
