Organic chemodosimeter for cyanide: A nucleophilic approach

Out of the all anions cyanide is one of the most threaten for environmental and social system and abundance of cyanide in environment generate not only from industrial waste but also from the biological process of fungal and algae. It has very much toxic effect, after a certain limit it may cause to death. The interest for qualitative and quantitative detection of cyanide is growing on. Detection rely on the change in absorption and emission properties of probe upon binding with cyanide is important because of its simple analysis technique. Cyanide is a good nucleophile and this property can be very much useful to develop organic probes to detect its presence. Here this review deals with the organic chemodosimetric probes for cyanide, more specifically the detection mechanism is driven by the nucleophilic attack of cyanide ion to the probe. Discussed organic probes are divided into some classes according to their structural features and functional group present in the probe. (C) 2015 Elsevier B.V. All rights reserved.
