摘要：

(Figure Presented) The color purple: A siloxy-functionalized benzamide (see picture) is a highly efficient fluoride ion sensor in water. The sensor, which is activated when the O-Si bond is cleaved by fluoride ions, provides two independent modes for signal recognition. In colorimetric mode, the fluoride ion concentration is transformed into a fluorescence signal that can be observed directly with the naked eye. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, weinheim.
