The ability to grow covalent organic framework (COF) films allows for studying their properties as solid layers and enables the incorporation of these materials into a variety of functional devices. Here, we report on the fabrication of COF films and coatings by electrophoretic deposition (EPD). We demonstrate that the EPD technique is suitable for depositing COFs featuring two- and three-dimensional structures linked by imine or boronate ester bonds, namely, BDT-ETTA COF, COF-300, and COF-5. For the deposition, COF nanoparticle suspensions are prepared by dispersing the as-synthesized bulk materials in solvents with low dielectric constants. Subsequently, two electrodes are immersed into the COF particle suspensions, and upon inducing electric fields ranging from 100 to 900 V cm(-1), COFs are deposited as films on the positively charged electrode. Through EPD, within 2 min, large-area films of up to 25 cm(2) are obtained on smooth or corrugated surfaces. COF films prepared by EPD feature an inherent textural porosity and tunable thickness, demonstrated from 400 nm to 24 mu m. By controlling the deposition parameters such as duration, particle concentration, and applied potential, deposits of precise thickness can be produced. Furthermore, codepositions of different COFs as well as COF/Pt nanoparticles from mixed suspensions are demonstrated. The film morphologies obtained by EPD are shown to be advantageous for catalysis, as demonstrated for sacrificial agent-free photoelectrochemical water reduction. Here, BDT-ETTA COF photocathodes show a strongly increased photocurrent density compared to the respective dense and oriented films. Typical BDT-ETTA COF/Pt nanoparticle hybrid films exhibit photocurrent densities of over 100 mu A cm(-2). The rapid and scalable deposition of COF particles as films and coatings through EPD is a versatile addition to the toolbox of COF film fabrication techniques, allowing for tailoring COF film architectures for desired functionalities.

SDS of cas: 123-11-5. The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

BACKGROUND Deep eutectic solvents (DESs) are prepared by mixing solid organic precursors to form a liquid driven from strong hydrogen-bond interactions. The physical and chemical properties of these compounds have been widely investigated, and it has been shown that they are benign media for biotransformations, organicsynthesis, biodieselpreparation, and a sustainable media for nanoscale and functional materials. RESULTS This study is the first report on the synthesis of n-TiO2-P25@TDI@DES (urea: ZnCl2) with photo catalytic activity. This nano photocatalyst was obtained through covalent grafting of TiO2-P25 nanoparticles to an inexpensive and highly reactive linker (2,4-toluene diisocyanate). The presented nano photocatalyst has been employed as a covalently grafted Lewis acidic deep eutectic solvent to oxidize various primary benzyl alcohols to their corresponding carbonyl compounds by sodium nitrate as oxidant, under visible light exposure. CONCLUSION This highly efficient nanocatalyst was investigated by various characterization techniques including fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM with EDX), and elemental analysis. Owing to its enhanced catalytic activity, thermal stability, and environmentally friendly nature, the present method can be regarded as an attractive green chemistry approach.

Fe3O4@SiO2@(CH2)(3)-urea-quinoline sulfonic acid chloride, as a novel and efficient nanomagnetic catalyst bearing urea linkers, was designed, synthesized and then fully characterized by using various techniques. To investigate the catalytic activity of the described catalyst, it was used for the synthesis of coumarin containing 1,4-dihydropyridines (DHPs), through a condensation reaction of aromatic aldehydes, 4-hydroxycoumarin, and ammonium acetate under solvent-free conditions. This procedure includes important aspects like simple procedure, simplicity of product isolation using water, decreasing the temperature of reaction, disuse of solvent, high to excellent yields, environmentally benign reaction conditions and short reaction times. Also, the presented catalyst was recycled and reused for at least five times with only a negligible decrease in its catalytic activity. The applied catalyst has both acidic and H-bond donor-acceptor sites so that it can use as a dual role catalytic system. (C) 2020 Elsevier B.V. All rights reserved.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

The chemical composition of the volatile fraction from Galium verum L. (leaves and flowers) and Cruciata laevipes Opiz (whole plant), Rubiaceae, was investigated. Samples from these two plant species were collected at full bloom in Val di Susa (Western Alps, Turin, Italy), distilled in a Clevenger-type apparatus, and analyzed by GC/FID and GC/MS. A total of more than 70 compounds were identified, making up 92%-98% of the total oil. Chemical investigation of their essential oils indicated a quite different composition between G. verum and C. laevipes, both in terms of the major constituents and the dominant chemical classes of the specialized metabolites. The most abundant compounds identified in the essential oils from G. verum were 2-methylbenzaldheyde (26.27%, corresponding to 11.59 mu g/g of fresh plant material) in the leaves and germacrene D (27.70%; 61.63 mu g/g) in the flowers. C. laevipes essential oils were instead characterized by two sesquiterpenes, namely beta -caryophyllene (19.90%; 15.68 mu g/g) and trans-muurola-4(15),5-diene (7.60%; 5.99 mu g/g); two phenylpropanoids, benzyl alcohol (8.30%; 6.71 mu g/g), and phenylacetaldehyde (7.74%; 6.26 mu g/g); and the green-leaf alcohol cis-3-hexen-1-ol (9.69%; 7.84 mu g/g). The ecological significance of the presence of such compounds is discussed.

Novel sulfonated carbon-coated magnetic nanoparticles (SCCMNPs; Fe3O4@C@OSO3H) were designed, synthesized, characterized, and applied as an efficient nanocatalyst for green synthesis of coumarin derivatives through Pechmann condensation. The Fe3O4@C@OSO3H was manufactured through a simple and inexpensive two-step procedure and characterized by FTIR, EDX, XRD, SEM, TEM, DLS, VSM, and TGA techniques. It was identified as an efficient heterogeneous catalyst in the Pechmann condensation of phenol derivatives and beta-ketoesters, leading to high-yield coumarin derivatives under solvent-free conditions. The Fe3O4@C@OSO3H removed after reaction finishing point by an external magnet, and it was reused fifteen times at the same conditions. Besides, theoretical studies were carried out using B3LYP/6-311++G(d,p) to more consideration of the reaction mechanism. The study of the frontier molecular orbitals, NBO atomic charges, molecular electrostatic potential of reactants, as well as Pechmann condensation mechanism was known very useful in suitable reactant choice. The reaction was performed through the electrophilic attack, dehydration, and trans-esterification, respectively. [GRAPHICS] .

Silver nanoparticles were fabricated in the presence and absence of light with silver nitrate and aqueous extract of Prunus cerasifera leaf via facile and one-pot green method. P. cerasifera leaf extract reduced and stabilized the nanoparticles with phytometabolites expunging the need for addition of external reducing agents. Optimized silver nanoparticle syntheses was done with variations in leaf extract concentration, time, temperature, and molarity for deciphering the photocatalytic, antifungal, and antibacterial potential of synthesized nanoparticles. Optical, compositional, and morphological analyses of the synthesized nanoparticles were done by UV-visible spectrometry (UV-Vis), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Formation of silver nanoparticles was confirmed firstly through UV-Vis by exhibition of peaks with 400-450 nm. FTIR confirmed the presence of major organic groups responsible for reduction of nanoparticles. AFM confirmed the spherical morphology of the synthesized nanoparticles with remarkable dispersion without any agglomeration. Phytochemical analysis for P. cerasifera leaf metabolites was done by GC-MS. Spherical nanoparticles having a size range of 57-144 nm were obtained with face-centered cubic crystals. The average crystallite size obtained from XRD spectra was 2.34 nm. Enhanced photocatalytic first-order kinetics were obtained for persistent organic pollutants, i.e., crystal violet, methylene blue, and malachite green (R-2 = 0.99, 0.99, 0.98) in less than 15 min. Biomedical and agricultural significance as an antibiotic drug and utilization as a fungicides substitute was explored against nine resistant microbes. Statistically significant variations were analyzed via one-way analysis of variance (ANOVA) and Kruskal-Wallis test and specific multi comparison tests. Active to highly active inhibition zones manifested the use of biogenic silver nanoparticles as potential candidate for applications in biological arenas and as environmental remediators.

Safety of 4′-Hydroxyacetophenone. The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.

The catalytic transformation of aryl esters to hydroxyacetophenonesviaFries rearrangement over solid acids is of interest to avoid the use of corrosive and toxic Lewis and Bronsted acids traditionally applied. Microporous zeolites are known to catalyze the reaction of simple substrates such as phenyl acetate, but their application to substituted derivatives has received limited attention. To refine structure-activity relationships, here we examine the impact of various parameters including the solvent polarity, water content, acidic properties, and framework type on the reaction scheme in the Fries rearrangement ofp-tolyl acetate over common solid acids. The results confirm the importance of providing a high concentration of accessible Bronsted acid sites, with beta zeolites exhibiting the best performance. Extension of the substrate scope by substituting methyl groups in multiple positions identifies a framework-dependent effect on the rearrangement chemistry and highlights the potential for the transformation of dimethylphenyl acetates. Kinetic studies show that the major competitive path of cleavage of the ester C-O bond usually occurs in parallel to the Fries rearrangement. The possibility of sequentially acylating the resulting phenol depends on the substrate and reaction conditions.

The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

This study aimed to characterize the antioxidant potential, bioactive and volatile compounds of the stones from fruits of Cornus mas. Both fresh and roasted stones show a high antioxidant potential (166.48-509.74 mu mol TE/g dw stones), which significantly depends on the cultivars. The roasted stones preserved 43.6% (DPPH; ‘Raciborski’) to 97.2% (FRAP; ‘Alesha’) of the antioxidant activity of the non-roasted stones. In the stones, two iridoids and ellagic acid were determined. During roasting, loganic acid remained stable, whereas cornuside was completely degraded. The analyses showed a 30-fold increase in the concentration of ellagic acid and in the formation of two of its derivatives. The major aroma compound of the roasted stones was furfural, but we also identified 18 pyrazine derivatives. This study is the first attempt to valorize Cornelian cherry stones via roasting. The roasted stones can be a coffee substitute, or aromatic and bioactive additions to cereal coffees.
