title: Controlling ion-sensing specificity of N-amidothioureas: from anion-selective sensors to highly Zn(2+)-selective sensors by tuning electronic effects.
abstract: 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 Zn(2+) in aqueous solution and in cells. N-Amidothioureas can therefore be adjusted from anion-selective sensors to Zn(2+)-selective sensors by varying the electronic effects of their substituents.
