“…The Job's plot for compexation of sensor with CN -ion showed a maximum titration occured in mol fraction ratio of 0.5 by fluorescence spectra. It showed one-to-one binding between S1 with ion CN - [11] and indicates the formation of receptor-anion complex with a stoichiometric ratio of 1:1 [26].…”

“…4-[(1E)-2-(4-hydroxyphenyl)ethenyl]-1-allylpyridinium bromide (HPEAPB) compound is also used as colorimetry sensor to detect CN -ion, because this sensor has a high selectivity and fast response with LOD value equals 3.4 × 10 6 M [10]. A compound diluted in DMSO/HEPES buffer was used to detect CN -ion, the LOD of CN -was measured through UV-visible titration experiment, LOD value is 10.3 µM [11].…”

A novel fluorescent sensor 4-(1H-benzimidazol-2-yl)-2-methoxy-phenol derivative was synthesized. Solution of 4-(1H-benzimidazol-2-yl)-2-methoxy-phenol (1 × 10 -7 M) in DMSO displays highly sensitives and rapid respons to CN -ion [values of LOD = 1.8 × 10 -6 M and Ka = 2.5 (± 0.26) × 10 6 M -1 ]. Sensor 4-(1H-benzimidazol-2-yl)-2-methoxy-phenol coordinated with CN -ion form with a 1:1 binding stoichiometry.

Azoquinoline based sensor AZQ was designed and synthesized as a new molecular ion sensor containing an azo group in its structure. The structural characterization of AZQ was carried out using FTIR, NMR, mass, and elemental analysis. Then, the interaction of AZQ with anions was observed visually and UV–vis measurements were made in EtOH/H2O (1:1, v/v) solvent mixture. As a result of this investigation, it was determined that AZQ is a fast and highly selective sensor for CN− ions. The solution colour of AZQ changed from light yellow to orange only in the presence of CN− ions. The limit of detection of AZQ was calculated as 2.6 μmol/L from anion titration experiments. Also, to identify the interaction mechanism of AZQ with CN− ions, 1H NMR spectra of AZQ in the presence of CN− anions were recorded and the structure was proposed for AZQ-CN− host–guest complex.
