Abstract

Three new chemodosimeters 1–3 were prepared, and their chromogenic and fluorogenic behaviours toward various metal cations were investigated. Receptors 1–3 show an exclusive response toward Hg²⁺ and also distinguish Hg²⁺ from other metal cations by different colour changes in aqueous DMSO solution. Among them, receptor 1 also exhibits a pronounced Hg²⁺-induced fluorescence enhancement. Therefore, the receptor 1 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg²⁺ ion.
