A new thioamide derivative of 8-hydroxyquinoline-benzothiazole was prepared, and its fluorogenic chemodosimetric behaviors toward transition-metal ions were investigated. The thioamide derivative showed highly Hg²⁺-selective fluorescence enhancing properties (167-fold) in 30%aqueous acetonitrile solution. The selective and sensitive signaling behaviors were found to originate from the Hg²⁺ ion induced transformationof the very weak fluorescent thioamide derivative into a highly fluorescent amide analogue.
