Fluorescence modulation of naphthalene containing salicyl hydrazide-based receptor through aggregation-induced emission enhancement approach: Dual detection of lanthanum and cyanide ions in semi-aqueous medium

The sensing activity of naphthalene containing salicyl hydrazide-based fluorescence receptor has been improved through aggregation-induced enhanced emission mechanism approach in semi-aqueous medium. The receptor has been found to be selective toward Las

A pH tuning single fluorescent probe based on naphthalene for dual-analytes (Mg2+and Al3+) and its application in cell imaging

In this study, a naphthalene Schiff-basePwhich serves as a dual-analyte probe for the quantitative detection of Al3+and Mg2+has been designed. The proposed probe showed an ‘‘off-on’’ fluorescent response toward Al3+in etha

Spectrofluorimetric determination of hydrogen peroxide with 2-hydroxy-1-naphthaldehyde salicyloylhydrazone (HNSH) as the substrate for horseradish peroxidase (HRP)

The oxidation reaction of HNSH with H2O2 under the catalysis of HRP was studied in detail. The possible reaction mechanism was discussed. Under optimum experimental conditions, the oxidized product of HNSH had excitation and emission

Benzoyl hydrazine derivative P and synthesis and application thereof

The invention relates to detection of a fluorescence method on metal ions, and particularly relates to a benzoyl hydrazine derivative P which identifies and detects two different metal ions Mg andAl separately in different pH conditions. The structural formula of the benzoyl hydrazine derivative P is as shown in a formula (1). The preparation method of the benzoyl hydrazine derivative P comprises the following steps: firstly, carrying out hydrazinolysis on ethyl salicylate; carrying out a reaction with o-hydroxy naphthaldehyde at a molar ratio of 1 to 1 for 4 hours at 80 DEG C in anhydrous ethanol; cooling the mixture and separating out a solid and carrying out suction filtration; washing the mixture with a lot of water and anhydrous ethanol successively; and drying the solid to obtain a light yellow solid pure product P. The benzoyl hydrazine derivative P can be used for detecting Mg and Al separately in different pH conditions as a fluorescent probe. The benzoyl hydrazine derivative P is obtained by means of an effective synthetic means and shows relatively good selectivity on the metal ions Mg and Al separately. On a basis of an optimized experimental condition, the metal ions Mg and Al can be detected separately. The formula is as show in the description.

Synthesis, structural studies and catalytic activity of dioxidomolybdenum(VI) complexes with aroylhydrazones of naphthol-derivative

Reaction of the salicylhydrazone of 2-hydroxy-1-naphthaldehyde (H 2L1), anthranylhydrazone of 2-hydroxy-1-naphthaldehyde (H2L2), benzoylhydrazone of 2-hydroxy-1-acetonaphthone (H2L3) and anthranylhydrazone of 2-hydroxy-1- acetonaphthone (H2L4; general abbreviation H2L) with [MoO2(acac)2] afforded a series of 5- and 6- coordinate Mo(VI) complexes of the type [MoO2L1-2(ROH)] [where R = C2H5 (1) and CH3 (2)], and [MoO 2L3-4] (3 and 4). The substrate binding capacity of 1 has been demonstrated by the formation of one mononuclear mixed-ligand dioxidomolybdenum complex [MoO2L1(Q)] {where Q = γ-picoline (1a)}. Molecular structure of all the complexes (1, 1a, 2, 3 and 4) is determined by X-ray crystallography, demonstrating the dibasic tridentate behavior of ligands. All the complexes show two irreversible reductive responses within the potential window -0.73 to -1.08 V, due to Mo VI/MoV and MoV/MoIV processes. Catalytic potential of these complexes was tested for the oxidation of benzoin using 30% aqueous H2O2 as an oxidant in methanol. At least four reaction products, benzoic acid, benzaldehyde-dimethylacetal, methyl benzoate and benzil were obtained with the 95-99% conversion under optimized reaction conditions. Oxidative bromination of salicylaldehyde, a functional mimic of haloperoxidases, in aqueous H2O2/KBr in the presence of HClO4 at room temperature has also been carried out successfully.
