CH19541Investigation of CO2 Adsorption on Triethylenetetramine Modified Adsorbents of TETA(n)/Zr-TSCD
A new type of Zr-TSCD support was first synthesized and modified with triethylenetetramine (TETA). The functionalized material exhibits good thermal stability and a remarkable CO2 adsorption capacity.
A coordination polymer was successfully synthesised by mixing linkers and NiII, which displays a rare 2D + 2D → 3D inclined polyrotaxane topology. Furthermore, the resultant MOF can be used as a heterogeneous catalyst for the CO2 cycloaddition reaction.
A symmetric tetramethylcucurbit[6]uril-based porous supramolecular assembly exhibits the characteristics of the absorbed fluorophore guests (FGs). Interestingly, the resulting luminescent assemblies (FG@As) can respond to methanol.
CH19485Sensitive Detection of Argonaute2 by Triple-Helix Molecular Switch Reaction and Pyrene Excimer Switching
In this paper, we develop a simple fluorescence sensing platform for the sensitive detection of Ago2 on the basis of Watson–Crick and Hoogsteen base pairings and pyrene excimer switching.
CH19581Electrochemistry of Neodymium in Phosphonium Ionic Liquids: The Influence of Cation, Water Content, and Mixed Anions
Electrodeposition using ionic liquids has emerged as an environmentally friendly approach to recover critical metals such a neodymium. Here, we present the electrochemical behaviour of dissolved Nd salts in a series of phosphonium ionic liquids as a function of electrolyte composition and investigate the influence of electrode substrate.
CH19627Magnetic Nanoparticle Supported Ionic Liquid Phase Catalyst for Oxidation of Alcohols
A magnetic nanoparticle supported ionic liquid phase catalyst containing perruthenate anions was synthesised and employed in the oxidation of benzyl alcohols. Good yields, magnetic retrievability, and reusability of the catalyst are benefits offered by this method.
CH20044Synthesis and Study of Prototropic Tautomerism of 2-(2-Furyl)-1-hydroxyimidazoles
1-Hydroxyimidazoles may exist as two prototropic tautomers: N-hydroxyimidazoles and imidazole N-oxides. By means of 1H and 13C NMR spectroscopy it has been demonstrated that in the series of 2-(2-furyl)-1-hydroxyimidazoles, the N-hydroxy tautomeric form is stable in both chloroform and DMSO. According to UV/vis spectroscopy data, in ethanol the N-oxide tautomer is also present.
CH19666Fluorescence Enhancement Method for Enrofloxacin Extraction by Core–Shell Magnetic Microspheres
Novel kinds of γ-Fe2O3@SiO2-NH2-CMC/MOF5 and γ-Fe2O3@SiO2-NH2-CMC/IRMOF3 magnetic metal–organic framework (MOF) nanoparticles were prepared, which possess both magnetic characteristics and fluorescent properties. γ-Fe2O3@SiO2-NH2-CMC/IRMOF3 nanoparticles could be used for magnetic solid-phase extraction (MSPE) in enrofloxacin (Enr) experiments.
A novel bis(rhodamine) B hydrazone L, bearing two rhodamine chromophores, was synthesised and utilised for instant ‘naked eye’ probing of Fe3+, Bi3+, Cu2+, and Hg2+ in aqueous media.
A new mono-core dicationic ionic liquid containing piperazin-1,4-diium and chlorosulfonate is synthesised and its structure is characterised. The dual solvent–catalyst activity of the reusable ionic liquid is demonstrated for the synthesis of new dihydro[1,2,4]triazolo[1,5-a]pyrimidines. The new method avoids the use of hazard solvents and employs a cost-effective workup procedure.
