“…Moreover, detection limits of the aforementioned anions in the present work were found to be superior than most of sensors reported so far. [8,31,34,35] Considering the minimum permissible concentrations of these anions, BP-1 demonstrated impressive efficiency to detect these anions upto nano-molar range.…”

Three Bisphenol based economical sensors were developed from readily available reagents with single synthetic step. The bisphenols were obtained from reaction of 2,6-dimethylphenol with 4-hydroxybenzaldehyde (BP-1), 4-bromobenzaldehyde (BP-2) and 4-nitrobenzaldehyde (BP-3). The cyanide and fluoride ions induce visual colour changes which enabled their naked eye detection and distinguished them as well. All the three sensors were able to detect these anions upto a nano molar range. Selective detection of these two anions with paper strips experiments were demonstrate by taking the BP-1 as representative case. Again, among the sensors BP-1 was chosen to immobilize into the cellulose based hydrogel matrix.Resulting composite efficiently detect cyanide and fluoride ions in 100 % aqueous system which otherwise was not feasible owing to water insolubility of BP-1. The 1 cm 2 film containing 0.01 mmol of BP-1 can absorb 2 ppm of fluoride ion from standard aqueous solution of KF. The morphology study reveals a smooth and miscible distribution of BP-1 into the polymer matrix. Surface morphology of the composite changes upon treatment with cyanide solution. Both the solution and film based sensing of these anions were found to be reversible in nature. The substituent effect on anion binding ability of respective sensors were demonstrated experimentally and validated theoretically.

“…[42] However, F À , being the smallest and most negatively charged anion, creates the sturdiest H-bonding attraction with the polar protons resulting in better response towards PMA in compared to CN À . [1,17] The synthesized sensory probe was characterized by SCXRD, ESI-MS, FTIR and 1 H-NMR experiments. The anion sensing studies of PMA were accomplished by several spectroscopic tools, such as UV-Vis, photoluminescence, FT-IR, and 1 H-NMR spectroscopy; cyclic voltammetry etc.…”

A Harmonized Applied and Theoretical Exploration for Nanomolar Level Recognition of Perilous F⁻ and CN⁻ by Multichannel Chemosensor: Proposition of Hg²⁺‐Mediated Logic Gate Imitator

et al. 2020

An inimitable Schiff-base chemosensor PMA (9-anthracenecarboxaldehyde pentafluorophenylhydrazone) was premeditated and implicated with the aim of detecting F À and CN À in semiaqueous medium. Highly photostable, multichannel sensory probe, PMA (with 31 % quantum yield) exhibited amusing sensing efficiency towards F À and CN À by dint of colorimetric, fluorimetric as well as electrochemical alterations, with a very low detection limit (76 nM for F À and 92 nM CN À). However, all the experimental outcomes evidenced PMA to be more sensitive towards F À than CN À owing to the more electro-negativity and smaller size of F À. The spectroscopic characterizations of the chemosensor along with the sensing studies were performed by more than a few erudite analytical tools, whereas the theoretical calculations also substantiated the experimental consequences. Here the thorough investigation on the theoretical aspect was performed to ensure the effective and plausible reason behind different sensitivity towards these two perilous anions. Moreover, the recyclability of PMA upon simultaneous addition of F À /CN À and Hg 2 + also helped to intend a three input logical circuitry.
