An efficacious “naked-eye” selective sensing of cyanide from aqueous solutions using a triarylmethane leuconitrile

A triarylmethane dye 1 detects CN− from water and shows remarkable selectivity over other anions and dramatic color changes, in solution as well as when dyed. The pH stability of 1 in the range of 1.2–10.7 offers additional advantage in the sensing process under physiological conditions.
