Abstract

A rhodamine-based sensor 1 was designed and synthesized by incorporation the rhodamine fluorophore and ionophore NS₂ with high affinity to Hg²⁺. Sensor 1 exhibits a high selectivity and an excellent sensitivity and is a dualresponsive colorimetric and fluorescent Hg ²⁺-specific sensor in aqueous buffer solution. In addition, the 1:1 binding mode was proposed based on the ¹H NMR and ES(+)MS studies.
