To achieve high photovoltaic performance of bulk hetero-junction organic solar cells (OSCs), a range of critical factors including absorption profiles, energy level alignment, charge carrier mobility and miscibility of donor and acceptor materials should be carefully considered. For electron-donating materials, the deep highest occupied molecular orbital (HOMO) energy level that is beneficial for high open-circuit voltage is much appreciated. However, a new issue in charge transfer emerges when matching such a donor with an acceptor that has a shallower HOMO energy level. More to this point, the chemical strategies used to enhance the absorption coefficient of acceptors may lead to increased molecular crystallinity, and thus result in less controllable phase-separation of photoactive layer. Therefore, to realize balanced photovoltaic parameters, the donor-acceptor combinations should simultaneously address the absorption spectra, energy levels, and film morphologies. Here, we selected two non-fullerene acceptors, namely BTPT-4F and BTPTT-4F, to match with a wide-bandgap polymer donor P2F-EHp consisting of an imide-functionalized benzotriazole moiety, as these materials presented complementary absorption and well-matched energy levels. By delicately optimizing the blend film morphology, we demonstrated an unprecedented power conversion efficiency of over 16% for the device based on P2F-EHp:BTPTT-4F, suggesting the great promise of materials matching toward high-performance OSCs.

An article Facile synthesis of hydrothermally stable mesoporous ZSM-5 zeolite from Al- SBA-16 via steam assisted crystallization WOS:000525171600023 published article about DRY-GEL CONVERSION; CATALYTIC PERFORMANCE; HIERARCHICAL ZEOLITES; N-HEPTANE; DESILICATION; ADSORPTION; SILICA; SIZE; CRACKING; MCM-41 in [Kamil, M.

In this work, Al grafted SBA-16 (Al-SBA-16) is converted into a fully crystalline hierarchical mesoporous ZSM-5 zeolite with hydrothermal stability by steam assisted crystallization under controlled conditions. The secondary mesoporosity is due to reorganization and recrystallization events happening upon steaming the precursor. Two mesoporous aluminosilicates (Al-SBA-16s) are used as the precursors of zeolites. The precursors are obtained by post-synthetic Al grafting on the silica walls of SBA-16 with aluminium isopropoxide and sodium aluminate. Mesoporous ZSM-5 zeolites obtained from the Al-SBA-16 precursors and commercial ZSM-5 are characterized using XRD, XRF, FT-IR, TEM, N-2 adsorption, Al-27 and Si-29 MAS NMR, and TPD of NH3. The results indicated the presence of intraparticle mesoporosity in the prepared mesoporous zeolites and they have comparable crystallinity with commercial ZSM-5. Catalytic activity of the synthesized mesoporous zeolites in benzylation of mesitylene is found to be comparatively more than commercial ZSM-5, which shows existence of micro/meso hierarchical structure in the mesoporous ZSM-5 zeolites. The aluminium sources, aluminium isopropoxide and sodium aluminate have a remarkable influence on the textural, acidity, and hydrothermal stability characteristics of the synthesized mesoporous ZSM-5 zeolites.

An article Metal-free photoredox-catalysed formal C-H/C-H coupling of arenes enabled by interrupted Pummerer activation WOS:000508320900002 published article about ARYL SULFOXIDES; ALLOSTERIC INHIBITORS; ELECTRON-TRANSFER; ALPHA-ARYLATION; LIGHT; SALTS; TRANSFORMATIONS; PSEUDILINS; REDUCTION; SULFONIUM in [Aukland, Miles H.; Siauciulis, Mindaugas; West, Adam; Perry, Gregory J.

Aryl-aryl cross-coupling constitutes one of the most widely used procedures for the synthesis of high-value materials that range from pharmaceuticals to organic electronics and conducting polymers. The assembly of (hetero)biaryl scaffolds generally requires multiple steps; coupling partners must be functionalized before the key bond-forming event is considered. The development of selective C-H arylation processes in arenes-which sidestep the need for prefunctionalized partners-is thus crucial for streamlining the construction of these key architectures. Here we report an expedient, one-pot assembly of (hetero)biaryl motifs using photocatalysis and two non-prefunctionalized arene partners. The approach is underpinned by the functionalization of a C-H bond in an arene coupling partner using the interrupted Pummerer reaction. A unique pairing of the organic photoredox catalyst and the intermediate dibenzothiophenium salts enables highly selective reduction in the presence of sensitive functionalities. The utility of the metal-free, one-pot strategy is exemplified by the synthesis of a bioactive natural product and the modification of complex molecules of societal importance.

Here, we report on a reproducible one-pot synthesis of high-quality and monodispersed CdS semiconducting nanocrystals (NCs) by mixing precursors cadmium acetate and elemental sulfur into the new solvent system of dibenzyl ether and oleylamine without using any extra reagent or precursor activator. The NCs (5 nm) exhibited a dominant band-edge emission with a good photoluminescence quantum yield of 13.76% without trap emission. The CdS NCs were characterized using UV?Vis and photoluminescence spectroscopy, electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The practical efficiency of the synthesized NCs was proved by applying the synthesized CdS NCs as the tracer in the engineering of an immunosandwich biosensor to evaluate the cardiac troponin (cTn) marker for the diagnosis and monitoring of myocardial infarction (MI). The biosensor revealed significant analytical efficiency with the limit of detection of 2 ng L-1 and the linear dynamic range of 5?1000 ng L-1, which is lower than the existing cutoff values (13?20 ng L-1). Having capitalized on the anodic stripping voltammetry method, the screen-printed biosensor could efficiently detect the cTn markers. Therefore, the biosensor is proposed to be used in clinical settings for fast, sensitive, and accurate monitoring of cTn markers.

Optical tissue clearing using dibenzyl ether (DBE) or BABB (1 part benzyl alcohol and 2 parts benzyl benzoate) is easy in application and allows deep-tissue imaging of a wide range of specimens. However, in both substances, optical clearing and storage times of enhanced green fluorescent protein (EGFP)-expressing specimens are limited due to the continuous formation of peroxides and aldehydes, which severely quench fluorescence. Stabilisation of purified DBE or BABB by addition of the antioxidant propyl gallate efficiently preserves fluorescence signals in EGFP-expressing samples for more than a year. This enables longer clearing times and improved tissue transparency with higher fluorescence signal intensity. The here introduced clearing protocol termed stabilised DISCO allows to image spines in a whole mouse brain and to detect faint changes in the activity-dependent expression pattern of tdTomato.

Nowadays, environmental pollution by microplastics (<5 mm; MP) is a major issue. MP are contaminating marine organisms consumed by humans. This work studied MP contamination in two bivalve species of commercial interest: blue mussel (Mytilus edulis) and common cockle (Cerastoderma edule) sampled on the Channel coastlines (France). In parallel, 13 plastic additives and 27 hydrophobic organic compounds (HOC) were quantified in bivalves flesh using SBSE-TD-GS-MS/MS to explore a possible relationship between their concentrations and MP contamination levels. MP were extracted using a 10% potassium hydroxide digestion method then identified by mu-Raman spectroscopy. The proportion of contaminated bivalves by MP ranged from 34 to 58%. Blue mussels and common cockles exhibited 0.76 +/- 0.40 and 2.46 +/- 1.16 MP/individual and between 0.15 +/- 0.06 and 0.74 +/- 035 MP/g of tissue wet weight. Some HOC and plastic additives were detected in bivalves. However, no significant Pearson or Spearman correlation was found between MP loads and plastic additives or HOC concentrations in bivalve tissues for the two species. (C) 2019 Elsevier Ltd.

We report an efficient procedure for the synthesis of pillared MWW zeolites (MCM-36) via integrating intercalation and hydrolysis of tetraethyl orthosilicate (TEOS) into one step. Specifically, two specially selected surfactants with more hydrophilicity instead of the conventional swelling agent cetyltrimethylammonium bromide (CTAB) were employed to increase the interlayer wetting ability and water content. The resultant intercalation and hydrolysis of TEOS occur concurrently in a confined interlayer microenvironment with enriched interlayer water and basic hexamethyleneimine (HMI). It is found that the wetting ability of swelling surfactants has a profound effect on pillarization efficiency, resulting in the different degrees of order of the layered structure, pore-size distribution, and accessibility of the acid sites of MCM-36. MCM-36 prepared using a gemini-type surfactant as a swelling agent shows a highly long-range ordered structure and enhanced catalytic activity for alkylation of benzene with benzyl alcohol compared to the one produced using conventional CTAB as a swelling agent.

The analysis of dust collected on the filters installed in the heating, ventilation, and air-conditioning (HVAC) systems, filter forensics, is a useful approach to explore concentration, size distribution, and composition of indoor particles. The extraction of dust from filters represents one of the biggest challenges to obtain accurate results from filter forensics. Although vacuuming is one of the most common dust extraction techniques, it is unclear how efficient it is and whether it provides a representative sample in terms of particle size. In this article, we used a high-capacity vacuum sampler to extract dust from 20 filters artificially loaded with well-characterized test dust as well as from 41 filters naturally loaded in residential HVAC systems. After all extractions, we recovered 0.1-5.5 g and 0.02-11.4 g of dust from the artificially and naturally loaded filters, respectively. These ranges were equivalent to 11.3-52.2% and 1.8-72.9% recovery efficiency, the ratio of dust recovered to the dust loaded in the filters. Multiple extractions were found to be an effective strategy to add to the recovery to enable filter forensics for the detection of multiple analytes. The recovered samples were slightly over-representative of particles greater than 10 mu m. Therefore, caution should be taken when applying filter forensics for studying contaminants associated with smaller particles. Copyright (c) 2020 American Association for Aerosol Research

Transition metal-catalyzed single bond metathesis has recently emerged as a useful strategy for functional group transfer. In this work, we explored the mechanism and reactivity profile of Pd/PhI-cocatalyzed C-P bond metathesis between aryl phosphines using density functional theory (DFT) calculations. The overall single bond metathesis involves two Pd(ii)-catalyzed C-P reductive eliminations and two Pd(0)-catalyzed C-P oxidative additions, which allows the reversible C-P bond cleavage and formation of the phosphonium cation. Distortion/interaction analysis indicates that the facile C-P bond cleavage and formation of the phosphonium cation are due to the involvement of coordinating aryl phosphine in the process. In addition, the substituent effects on the reaction kinetics and thermodynamics of metathesis were computed, which provides helpful mechanistic information for the design of related single bond metathesis reactions.

A mild and efficient protocol for O-arylation of alcohols and phenols (ROH) by triarylsulfonium triflates was developed under transition-metal-free conditions. Various alcohols, including primary, secondary and tertiary, and phenols bearing either electron-donating or electron-withdrawing groups on the aryl rings were smoothly converted to form the corresponding aromatic ethers in moderate to excellent yields. The reactions were conducted at 50 or 80 degrees C for 24 h in the presence of a certain base and showed good functional group tolerance. The base-mediated arylation with asymmetric triarylsulfonium salts could selectively transfer the aryl groups of sulfoniums to ROH, depending on their inherent electronic nature. The mechanistic studies revealed that the reaction might proceed through the nucleophilic attack of the in situ formed alkoxy or phenoxy anions at the aromatic carbon atoms of the C-S bonds of triarylsulfonium cations to furnish the target products.
