✦ Synopsis

The synthesis and evaluation of two new ratiometric chemosensors for the quantification of potentially toxic free Zn 2+ ions in aqueous solutions are described. Both sensors show high selectivity for Zn 2+ over other cations, and are functional at environmentally relevant pH with detection limits of 0.05 lM for free Zn 2+ .
