Abstract:
The method of formation of low-molecular-weight organogelators via modifications in the substituents
has been demonstrated. The organogelator formed can selectively sense cyanide ions in the gel and
solution phases. Interaction of cyanide with acylhydrazone was noticeably visible to the ‘‘naked eye’’
and was proved using 1H NMR titrations. Notably, the ligand has been successfully explored for the
recognition of cyanide ions in food samples. Additionally, low-cost cotton swabs coated with the
organogelator showed rapid, on-site recognition of cyanide ions. The structure–property relationship
discovered in the given study provides insight into the development of novel, cost-effective
multifunctional materials.
