A series of new compounds (1-12) containing 1,5-diaza-fluorenone, 1,10-phenanthroline-5,6-dione, ferrocene-1,1ʹ-dione, anthracene-9-carbaldehyde have been synthesized and optimized. The nanomaterials were also developed successfully. ) by theoretical investigation, UV-vis, and fluorescence experiments, and compound 6 displayed the strongest binding ability for AcO − ion among the synthesized compounds. Theoretical investigation analysis revealed that the intramolecular hydrogen bond existed in the structure of compound 6 and the roles of molecular frontier orbitals in molecular interplay. In addition, compound 6 showed wide antibacterial activity for colon bacillus, typhoid bacillus, and Pseudomonas aeruginosa, and inferior activity for hay bacillus and Staphylococcus aureus. This series of acylhydrazone nanomaterials showed double properties, anion binding ability, and antibacterial activity.

A series of colorimetric anion probes 1–6 containing OH and NO2 groups were synthesized, and their recognition properties toward various anions were investigated by visual observation, ultraviolet–visible spectroscopy, fluorescence, 1H nuclear magnetic resonance titration spectra and theoretical investigation. Nanomaterials of three compounds 2–4 were prepared successfully. Four compounds 3–6 that contain electron-withdrawing substituents showed a high binding ability for AcO−. The host–guest complex formed through a 1:1 binding ratio, and color changes were detectable during the recognition process. Theoretical investigation analysis revealed that an intramolecular hydrogen bond existed in the structures of compounds and the roles of molecular frontier orbitals in molecular interplay. These studies suggested that this series of compounds could be used as colorimetric probes to detect of AcO−.

“…31 Although, so far a wide variety of sensors has been reported for the detection of cyanide ion, improving the detection selectivity and sensitivity in the context of interference from coexisting anions such as uoride, acetate and dihydrogen phosphate and compatibility within an aqueous environment have been still challenging. [32][33][34] Therefore, the search for receptors which can sense cyanide ion sensitively and selectively in aqueous solution is still on. It is well known that the main disadvantage, with most of the traditional chemosensors which depend on the H-bonding moieties, is the lack of selectivity.…”

Five new chemosensors (R1-R5), possessing benzoquinone as signaling unit and imidazole as H-bond donor unit, for cyanide sensing have been rationally designed, synthesized and characterized by NMR and mass spectroscopy. The structure of R5 was confirmed by single crystal XRD studies. These receptors exhibited prominent visual colour change toward cyanide ion over other common anions in aqueous HEPES buffer-DMF (9:1 v/v) medium. The complexation of receptor-CNhas been addressed by UV-Vis, fluorescence and 1 H NMR spectra and was supported by electrochemical and DFT studies. The mechanism of sensing involves formation of H-bond between imidazole N-H and CNion. The stoichiometry of the receptor-CNcomplexes was found to be 1:2 (receptor-CN -) and the detection limit was observed to be in the range of 1.1-3 nM. The test strips based on R5 were fabricated, which could act as convenient and efficient CNtest kits. Notably, the novelty of the present investigation is that the receptor R5 selectively senses CNion in solid, aqueous and gas phases i.e. 'a complete receptor'.
