Cyanides being highly poisonous to living beings and pollutants to our environment are among the most important anions studied over the years. As cyanide usage continues to sky-rocket, it is extremely important and high time that chemists devised methods for their detection to ensure harmless usage and safer working conditions for people coming into contact with cyanide and its compounds, day in day out. In this book, an attempt has been made to provide an in-depth commentary of literature for the synthesis of fluorescent dyes and mechanisms for the molecular recognition and detection of cyanide ions. It also covers some current entropy on colorimetric and fluorescent organic chemical probes for the detection and quantification of cyanide anions via fluorogenic and chromogenic procedures.

Chemosensors for anions and cations detections have been extensively used in several disciplines, including pharmacology, environmental science, biology, and chemistry. This field which is a division of supramolecular chemistry has been known for more than 150 years. It deals with chemosensors that recognize and detect anions and cations via optical or electrochemical signals. Today, a sustainable variety of chemosensors are established to detect both anions and cations. Additionally, chemosensors can be used to construct a sensory device and extract, and separate anions and cations. Chemosensors can detect toxic anions such as fluoride and cyanide as well as cations like mercury. Thus, chemosensors have become an attractive area of supramolecular chemistry. This chapter focuses on both colorimetric and fluorometric optical chemosensors and their application for anions and cations detections.
