Fluorescein-based Fluorescent and Colorimetric Chemosensors For Copper in Aqueous Media
Two new fluorescein-based chemosensors for Cu 2+ were designed with highly selective “off-on” behavior, one of them working in both absorption and emission, the other only in absorption. Binding to Cu 2+ binding is reversible, as indicated by the bleaching of the color when the metal is extracted. The compounds form the basis for rapid, selective and sensitive Cu 2+ chemosensors in aqueous media. © 2011 Elsevier Ltd. All rights reserved.
