摘要
In recent decades, the progress in excellent receptors for anions has attracted considerable attention in the field of supramolecular chemistry, due to the fact that anions bear immense importance in connection to their role in biology, chemical and environmental issues. Among these methods, the reaction-based probes, coined here as "reactive" probes, which involve the use of special chemical reactions induced by target analytes, provide us versatile means for investigating a wide range of analytes with superior analyte selectivity. Through the ingenious molecular design, it is expected that new reactive chemosensors towards anions can be designed and developed by virtue of the different optical properties before and after the reaction. Since the first report in 1992, more and more good optical anion chemosensors have been successfully obtained taking advantage of the reactive approach. This paper reviews the recent progress in the field of the fluorescent and colorimetric anion chemosensors (including cyanide, fluoride, hydrogen sulfite, hydrosulfide, hypochlorite, hypobromous acid/hypobromite and peroxynitrite anions) designed according to the special chemical reactions, and gives some outlooks for the further exploration of new optical anion chemosensors.
