Hg2+ selective fluorescent and colorimetric sensor: Its crystal structure and application to bioimaging

Abstract

(Chemical Equation Presented) A Hg2+-selective rhodamine 6G derivative bearing thiolactone moiety was synthesized, and its crystal structure with Hg2+ is presented to explain the binding mode. In addition, highly selective "off-on"-type fluorescent change upon the addition of Hg2+ was also applied to bioimaging. © 2008 American Chemical Society.
