Thiazole-based chemosensor: synthesis and ratiometric fluorescence sensing of zinc
摘要:
A new ratiometric and selective fluorescent chemosensor (1), based on thiazole for quantification of zinc ions in aqueous ethanol, was synthesized and investigated. The mechanism of fluorescence was based on the cation-induced inhibition of excited-state intramolecular proton transfer (ESIPT). (C) 2009 Elsevier Ltd. All rights reserved.
