摘要
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 Hg(2+) and also distinguish Hg(2+) from other metal cations by different colour changes in aqueous DMSO solution. Among them, receptor 1 also exhibits a pronounced Hg(2+)-induced fluorescence enhancement. Therefore, the receptor 1 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg(2+) ion.
