Abstract
Three new chemodosimeters 1–3 were prepared, and their chromogenic and fluorogenic behaviors toward various metal cations were investigated. Receptors 1–3 show exclusive response toward Hg2+ ion and also distinguish Hg2+from other metal cations by different color changes in DMSO aqueous solution (DMSO/H2O = 9/1). Among them, receptor 1 also exhibits a pronounced Hg2+-induced fluorescence enhancement. Thus, the receptor 1 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg2+ ion. The use of the test strip of the receptor 1 to detect Hg2+ was also reported.
