A novel microextraction method, termed microwave-assisted ionic liquid/ionic liquid dispersive liquid–liquid microextraction, has been developed for the rapid enrichment and analysis of triazine herbicides in fruit juice samples by high-performance chromatography. Instead using hazardous organic solvents, two kinds liquids, a hydrophobic (1-hexyl-3-methylimidazolium hexafluorophosphate) hydrophilic (1-butyl-3-methylimidazolium tetrafluoroborate), were used as extraction solvent dispersion...
A novel 5,10,15,20-tetra[4-(3,5-dioctoxybenzamide)phenyl]porphyrin and its transition metal complexes are reported in this paper. Their molecular structures were characterized by elemental analysis, IR spectra, 1HNMR spectra UV-Vis spectra. spectroscopic properties studied Raman fluorescence X-ray photoelectron (XPS). The quantum yields have been measured at room temperature. intensity of porphyrin ligand was stronger than that the complexes. In there much difference between due to changes...
In this work, a novel fluorescence sensor UiO-66-PSM based on post-synthetic modified metal-organic frameworks was prepared for the detection of berberine hydrochloride (BBH) in traditional Chinese herb Coptis. synthesized by simple Schiff base reaction with UiO-66-NH2 and phthalaldehyde (PAD). The luminescence quenching can be attributed to photo-induced electron transfer process from ligand BBH. exhibited fast response time, low limit, high selectivity Moreover, successfully applied...
Neurodegenerative diseases represent a cluster of conditions characterized by the progressive degeneration structure and function nervous system. Despite significant advancements in understanding these diseases, therapeutic options remain limited. The medicinal mushroom
The synthesis and characterization of a new unsymmetrical porphyrin liquid crystal, 5-(4-stearoyloxyphenyl)phenyl-10,15,20-triphenylporphyrin (SPTPPH2) its transition metal complexes (SPTPPM, M(II) = Zn, Fe, Co, Ni, Cu or Mn) are reported. Their structure properties were studied by elemental analysis, UV-Vis, IR, mass 1H-HMR spectroscopy. luminescent excitation emission quantum yields the S1 ? S0 fluorescence measured at room temperature. According to thermal studies, have higher stability...
Screening triplex DNA binders from complicated samples in a high-throughput fashion with good reproducibility without the requirement of an extra releasing step.
An innovative strategy for sustainably active oxygen capture using nitrogen (N2) instead of helium (He) as direct analysis in real-time (DART) gas is demonstrated this work. DART MS was carried out to analyze different polarity compounds including organophosphorus pesticides, amino acids, hormones, and poly brominated diphenyl ethers by He N2 gas, respectively. The unexpectedly characteristic ionization reactions, replacement reaction where the sulfur atom P=S group, were replaced atom,...
Molecularly imprinted polymers have received wide attention from various fields owing to their pre-designable, recognition ability, and practicality. However, the disadvantages of traditional embedding method, which include a slow rate, uneven site recognition, low binding capacity, incomplete template molecule elution, limit development molecular imprinting technology. Surface techniques been developed effectively solve these problems, different materials are used as carriers in synthesis...
In this work, laser‐enhanced in‐source decay (LEISD) technique of matrix‐assisted laser desorption/ionization Fourier transform ion cyclotron resonance mass spectrometry (MALDI‐FT‐ICR‐MS) was used to distinguish reducing and nonreducing carbohydrates. Interestingly, easier cleavage (1 → 2)‐linked glycosidic bonds for carbohydrates containing D‐fructofuranosyl units observed in MALDI‐FT‐ICR‐MS, which agreement with the result theoretical calculation by software package Gaussian 09....
