A coumarin-based dithiane (1) was synthesized for the selective detection of Hg2+ with respect to dual chromo- and fluorogenic changing events in an aqueous solution by the mercury-promoted transformation of a dithiane group into an aldehyde functional unit. The Hg2+-selective response of the chemodosimeter was clearly observed in aqueous buffer as well as in human blood plasma medium. (C) 2009 Elsevier Ltd. All rights reserved.
