β-Vinyl substituted calix[4]pyrrole as a selective ratiometric sensor for cyanide anion

摘要

A new calix[4]pyrrole-based, dual functional, chemodosimetric sensor was developed and studied as a cyanide selective indicator; complete color bleaching was observed even in the co-presence of an excess of other anions.rnCyanide anion is highly toxic to living animals; accordingly, any type of release into the environment can lead to serious problems. On the other hand, cyanide is used in various industrial processes, including gold mining and electroplating, enhancing the chance of unwanted release. Not surprisingly, therefore, there is growing interest associated with the development of cyanide selective receptors and sensors. Indeed, several sensor systems for cyanide anion detection have been reported to date including utilization of the complexation of cyanide with metal ion, with boronic acid, and with quantum dots.
