摘要：
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. (C) 2011 Elsevier Ltd. All rights reserved.
