Chromone-derived chemosensors: an experimental and theoretical study on cyanide detection.

This study introduces chromone-based probes designed for selective cyanide ion detection in acetonitrile. Through various spectroscopic methods, the probes demonstrated a colour change from colourless to yellow, enabling naked-eye detection of cyanide ions. The sensors exhibited high sensitivity (6.2 µM) and selectivity for CN^¯ ions over common anions. Computational analyses by FMO, NCI, QTAIM, NBO and EDD analysis confirmed the probes' suitability for cyanide detection. Overall, the synthesised compounds present a promising solution for practical applications in the field of cyanide ion sensing. [ABSTRACT FROM AUTHOR]
