Ecological and Economic Efforts in the Development of Molecular Sensors for the Optical Detection of Cyanide Ions

Abstract
Abstract Cyanide anions have wide use in industrial areas despite their high toxicity to the environment as waste; thus, numerous studies on the determination of this anion have been carried out. This review discusses recent progress in the colorimetric and fluorimetric detection of cyanide by nucleophilic addition or acid‐base reactions to different types of receptors by the chemodosimeter approach. Beyond sensor performance, we focus our analysis on the sustainable synthesis features of five representative families of probes based on small molecules. Some environmental and economic factors are considered (reaction mass efficiency, number of chemical changes, solvent greenness average, preliminary raw material cost, and energy implications), giving a complete picture of the current status of research in this detection field.
