Abstract

A highly selective colorimetric chemosensor 6,6′-((1E,1′E)-hydrazine-1,2-diylidenebis(methanylylidene))bis(2,4-dichlorophenol) (1) based on the combination of hydrazine and 3,5-dichloro-2-hydroxybenzaldehyde was designed and synthesized. Receptor 1 showed exclusive response toward cyanide by a color change from colorless to yellow in aqueous solution. The binding mode of 1-CN^- species was determined to be a 1:1 stoichiometry through Job plot, ¹H NMR titration, and ESI-mass spectrometry analysis. Also, the sensor 1 could be recyclable simply through treatment with a proper reagent such as hydrochloric acid.
