ABSTRACT:
Disclosed are a novel 8-hydroxyquinoline acetamide compound, an 8-hydroxyquinoline thioamide and use thereof. More specifically, disclosed are a novel 8-hydroxyquinoline thioamide compound suitable for use as a selective chemodosimeter that shows considerably high detection sensitivity to mercury ions, an 8-hydroxyquinoline acetamide compound as an intermediate thereof, preparation thereof, and a chemodosimeter for mercury ion-selective detection, the chemodosimeter comprising the 8-hydroxyquinoline thioamide compound. The compounds as disclosed herein exhibit considerably effective fluorescence specificity of an off-on type, detect a micromole of mercury ions from chemical and biological aqueous systems, and allow 100% desulfurization within 5 minutes, thus being considerably useful in the chemical industry.
