N-Amidothioureas bearing nitro groups showed different sensitivities to various anions, while those with methoxy moieties exhibited the sensitive and selective fluorescence turn-on property for Zn2+ in aqueous solution and in cells. N-Amidothioureas can therefore be adjusted from anion-selective sensors to Zn2+-selective sensors by varying the electronic effects of their substituents.
