| 英文摘要 | This work reports a facile strategy for the synthesis of water-soluble fluorescent probes Pyrl and Pyr2, which have carboxyl and hydroxyl group in the side chain of thioacetal moiety, respectively. Pyr1-2 exhibit exclusively selective turn-on fluorescence response towards Hg2+ over other cations, based on intramolecular charge transfer (ICT) mechanism. Upon addition of Hg2+, the thioacetal moiety in Pyr1-2 can be converted to aldehyde group, which is confirmed by H-1 NMR titration. The detection limits for Pyr1-2 are less than 1.80 nM in aqueous media, lower than the maximum allowable level of Hg2+ in drinking water by EPA. Moreover, Pyr2 have been successfully used for fluorescence imaging of Hg2+ in living cells, demonstrating potential application in biological science. |
