Abstract

A new multifunctional chemosensor 1 was developed for the detection of Mn²⁺, Zn²⁺ and Al³⁺. This sensor 1 detected Mn²⁺ ions through a distinct color change from colorless to yellow in MeCN-buffer solution. In addition, the sensor 1 showed significant fluorescence enhancements in the presence of Zn²⁺ ion and Al³⁺ ion, respectively, in an organic solvent DMF. Interestingly, the sensor 1 showed a good selectivity and sensitivity toward only Zn²⁺ ion in aqueous solution and was found to be reversible. In particular, this chemosensor could clearly distinguish Zn²⁺ from Cd²⁺. The binding modes of the complexes were determined to be a 1:1 complexation stoichiometry through Job plot, ¹H NMR titration, and ESI-mass spectrometry analysis.
