A highly selective "turn-on" water-soluble fluorescent sensor for gallium ion detection.

In this work, a novel sensor, ()-'-(3-(-butyl)-2-hydroxybenzylidene)thiophene-2-carbohydrazide (1), based on salicylaldehyde and thiophene hydrazide moieties was designed and synthesized. The single-crystal structure of 1 was achieved and studied for understanding its functional properties. The interaction and recognition abilities of 1 with different metal ions were investigated.

Controlled supramolecular interaction to enhance the bioavailability of hesperetin to targeted cancer cells through graphyne: a comprehensive study.

In the current study, the drug carrier efficiency of graphyne (GRP) for the transfer of the hesperetin (HPT) drug is evaluated for the first time. The GRP efficacy as a carrier is investigated using the density functional theory (DFT) technique to calculate various physiochemical characteristics such as dipole moment, bandgap, and chemical reactivity-descriptors for HPT, GRP and HPT@GRP complex. The non-covalent-interaction (NCI) plot indicated that GRP and HPT have weak interaction force, which is fundamental for the drug's noticeable offloading from the GRP carrier at its target location.

Structural conversion of three copper(ii) complexes with snapshot observations based on the different crystal colours and morphology.

Three novel Cu(ii) complexes [Cu(L)(MeOH)] (1), [Cu(L)(HO)] (2) and [CuL(HO)] (3) (L = ()-2-((2-hydroxy-4-methoxybenzylidene)amino)acetic acid) have been obtained in different time scales of reaction processing. Complexes 1 and 2 are kinetically controlled products and 3 is a thermodynamically stable product. Single crystal X-ray diffraction analyses revealed that 1 and 2 are binuclear complexes except for different coordination solvents.

Synthesis, crystal structures, and luminescent properties of Zn(ii), Cd(ii), Eu(iii) complexes and detection of Fe(iii) ions based on a diacylhydrazone Schiff base.

Acylhydrazone Schiff bases are rich in N and O atoms to coordinate with metal ions to form multidentate complexes. In this study, a novel diacylhydrazone Schiff base (' ,' )-','-bis(2-hydroxy-5-nitrobenzylidene)succinohydrazide (HL) was synthesized from the condensation of nitrosalicylaldehyde and succinic dihydrazide. The interactions of HL with common monovalent, divalent and trivalent metal ions were investigated by ultraviolet spectroscopy and fluorescence spectroscopy.

The enhancement of the D-A effect of an asymmetric Schiff base by introducing acetyl groups into diaminomaleonitrile: synthesis, red fluorescence and crystal structure.

An asymmetrical salen-type organic ligand was designed and synthesized by a new strategy developed using a precursor Ac-DMN, which is a diaminomaleonitrile (DMN) incorporated with an acetyl group. In this study, two types of asymmetrical ligands, namely Ac-DMN-salicylaldehyde (L) and Ac-DMN-4-,-diethyl-salicylaldehyde (L), and their Zn(ii) coordination complexes were studied. With the electron-pushing substituent, L showed interesting photoluminescence behaviour distinct from that of L.
