A convenient strategy that does not need the tedious modification of the π-conjugation moiety to constructnearinfrared (NIR) sensors is in high demand. In this study, we present the design and synthesis of a NIR Hg(II) turn-on fluorescent sensor BODIPY-SAN, which shows several advantages including (1) simple to be synthesized by only a predictable modification of the core structure of 6-hydroxyindole-based

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

A water-soluble turn-on fluorescent sensor for Hg(II) is described. Incorporation of soft thioether donors into an aniline-derived ligand framework that can be linked to a fluorescein platform affords sensor MS1, which shows a approximately 5-fold increase in integrated emission upon addition of 1 equiv of Hg(II). The synthesis and metal-binding properties of MS1 are discussed, and its ability to detect environmentally relevant concentrations of Hg(II) is demonstrated.
