Abstrak/Abstract
A novel receptor based on nitro group featuring with benzimidazole unit (S2) was successfully synthesized and applied to the anion (CN–, F– and H2PO4–) recognition. The S2 changed its colour for light yellow to dark yellow on addition of the anions in DMSO solvent. The LOD and Kass values determined by UV-visible titration was 2.8 × 10–6 M and 1.2 (± 0.25) × 106 M–1 for CN– ion; 1.14 × 10–6 M and 2.5 (± 0.25) × 106 M–1 for F– ion; and 1.23 × 10–5 M and 6.25 (± 0.177) × 106 M–1 for H2PO4– ion, respectively.
