Mercury ion is one of the common environmental pollutants. Organic mercury, especially methyl mercury, can be accumulated in marine organisms, and then transferred to the human body through the food chain, leading to brain Danielization and other chronic diseases. So, it’s very important to detect the Hg2+ which was one of the water pollutions. In this text, the authors prepared a fluorescent probe of Hg2+ based on rhodamine -thiophene conjugate. The probe was found to show a reversible dual chromo- and fluorogenic response toward Hg2+ likely due to the chelation-induced ring-opening of rhodamine Spiro lactam. And they can detect Hg2+ in 50% CH3CN/H2O buffered at pH6.0 and it exhibits high sensitivity and selectivity for sensing Hg2+. Besides, the determination of Hg2+ in both tap and river water samples displays satisfactory results.
