Yao, Ying;Fu, Xu-Mei;Hu, Jing-Han research published 《 Novel high sensitivity dual-channel chemosensor for detecting CN– based on asymmetric azine derivatives in aqueous media》, the research content is summarized as follows. Specific monitoring of trace levels of poisonous ions by naked eyes is still a significant challenge in the surroundings. Herein, the authors developed a novel asym. azine dual-channel sensor (HSD) applied for selectively detecting the CN– in the aqueous media. The selectivity and sensitivity of sensor HSD for anions sensing were studied by measuring the photophys. properties. HSD recognizes CN– with good selectivity and sensitivity, with an “off” fluorescence response and apparent color change (from colorless to yellow) under visible light and strong anti-interference to other common anions. According to fluorescence titration of sensor HSD to CN–, the detection limit is as low as 1.02 x 10-8 M. In addition, the reaction mechanism of the probe was studied by 1H NMR titration and DFT theor. calculations Finally, the test strips were prepared and verified to be a convenient and high-efficiency test kit for detecting CN– by naked eyes in the actual sample.

3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
