•A simple and easy-to-make colorimetric sensor for F− and CN− was designed and synthesized.•The receptor 1 could distinguish CN− selectively from other anions in aqueous medium.•CN− resulted in a color change of 1 from colorless to green in aqueous solution.•Solvent dependent naked-eye sensing.
A novel chemosensor based on azo linked Schiff base (receptor 1) was synthesized by simple condensation method. The sensor studies of receptor 1 disclose the selectivity toward fluoride and cyanide ion with a color change among the other common anions in aqueous medium. The binding affinity of receptor 1 was also enlightened by 1H NMR titration and DFT calculation.
