10,10-Bis[4-(4-aminophenoxy)-3-methylphenyl]-9(10H)-anthrone, as a new aromatic diamine, was synthesized from 9(10H)-anthrone by three-step procedure. Low-temperature polycondensation of this diamine with various aromatic dicarboxylic acid dichlorides produced a series of new cardo poly(ether amide)s with moderate to high inherent viscosities of 0.86-1.43 dL g(-1)while the weight-average and number-average molecular weights were in the range of 48,600-59,800 and 29,800-35,600 g mol(-1), respectively. All the polymers were readily soluble in polar solvents such asN,N-dimethylacetamide (DMAc),N,N-dimethylformamide,N-methyl-2-pyrrolidinone, dimethyl sulfoxide, and pyridine, and afforded transparent, flexible, and strong films upon casting from DMAc solvent. These polymers had glass transition temperatures of 254-297 degrees C, 10% weight loss temperatures of 493-505 degrees C, and char yields of 61-64% at 800 degrees C in nitrogen. All polymers were amorphous and their films exhibited tensile strength of 80.7-101.4 MPa, elongation at break of 8.0-12.8%, and tensile modulus of 1.9-2.6 GPa. These polymers had low moisture uptake in the range of 2.13-4.02% and high transparency with an ultraviolet-visible absorption cutoff wavelength in the 322-375 nm range.

The ring-expanded strategy in nonfullerene acceptors (NFAs) with the acceptor-donor-acceptor backbone has been reported to be an effective method to improve the fill factor (FF), open circuit voltage (VOC), and short circuit current (JSC) simultaneously in organic photovoltaics. However, design control is still missing in the ring-expanded strategy, and is urgently needed to further develop the origins and rules. To give insight into this strategy, a detailed theoretical study of the ring-expanded mechanism is performed on the systems comprising different 9,9 ‘-bifluorenylidene-based cores and 1,1-dicyanomethylene-3-indanone group. Some main parameters involved in photoelectric conversion mechanism under the donor excitation (DE) and/or acceptor excitation (AE) are assessed by changing the position and size of ring-expanded modes. The results show that the external ring-expanded modes can not only maintain the original advantage as much as possible, variations in sizes and positions also offer them an opportunity to regulate the aforementioned parameters systematically, leading to better improvement regardless of AE or DE. Thus, the steady improvement in performance mentioned previously is the key to overcoming the negative correlation among FF, VOC, and JSC. This insight and discovery of the ring-expanded strategy provides new design approaches for the next generation of NFAs.

I found the field of Materials Science; Physics very interesting. Saw the article NIR-to-vis photon upconversion in rubrenes with increasing structural complexity published in 2021.0. HPLC of Formula: C13H10O, Reprint Addresses Kazlauskas, K (corresponding author), Vilnius Univ, Inst Photon & Nanotechnol, Sauletekio Av 3, LT-10257 Vilnius, Lithuania.. The CAS is 119-61-9.

Rubrene is the most widely used triplet-triplet annihilation (TTA) emitter for NIR-to-vis photon upconversion (UC), however, strong singlet fission (SF) in the solid films quenches its emission and hampers practical TTA-UC applications. Herein, the issue was addressed by decorating the rubrene with sterically demanding 3,5-di-tert-butylphenyl side-moieties at the periphery and the core to result in 40-fold enhancement of the emission quantum yield. Nevertheless, the sterically crowded rubrenes were found to exhibit lower sensitized UC performance compared to the conventional rubrene, which was ascribed to inefficient triplet energy transfer from a sensitizer and poor TTA (for the core-modified rubrene only). By exploiting the distinct feature of rubrenes to simultaneously express both SF and TTA in the solid films, their TTA efficiency was assessed independently from TET in the sensitizer-free films. The results implied a trade-off between suppressed SF and enhanced TTA in the rubrene emitters, which could be addressed via careful selection of the degree of sterical hindrance and linking position of the side-moieties. Thorough analysis of the prompt and delayed fluorescence revealed that the bulky side-moieties at the periphery do not impede TTA, i.e., it is as efficient as that of unsubstituted rubrene, whereas these moieties linked directly to the core suppress TTA dramatically. The current study unveils an advantage of the peripheral linking vs. core linking pattern of rubrene emitters, thereby providing valuable insights for their rational modification towards improved NIR-to-vis UC efficiency in the solid state.

Media coverage of disasters potentially damages mental health. Moreover, its effects may differ as recipients may have different emotional responses toward media. The present study examined whether social capital, known to be protective against mental problems, influences a recipient’s emotional response toward news media broadcasting of natural disasters via newspapers, television and internet in Japan. Three social capital components, social participation, social support and cognitive social capital, were considered in the present study as each component reportedly had different effect on mental health. This nationwide cross-sectional survey was undertaken in 2015 among 1,200 Japanese citizens aged 15 to 79 years who were selected using the multi-stage sampling procedure. Data were collected via the drop-off pick-up method using a printed structured questionnaire. Negative and positive emotions were classified based on recipients’ responses against news media. Among 1,190 participants who reported emotions toward news media, 30.9% (368) had experienced any natural disasters, 37.4% (445) belonged to at least one formal or informal organization (social participation), 40.2% (478) had high social support, and 68.8% (819) had high cognitive social capital. High social support was associated with both reduced negative emotional response (OR 0.66, 95% Confidence Interval (CI) 0.47-0.93) and increased positive emotional response (OR 1.48, 95% CI 1.04-2.12) in multivariate analyses, while high cognitive social capital was only associated with increased positive emotional response (OR 1.62, 95% CI 1.11-2.37). These results suggest protective effects of social support and cognitive social capital against news media coverage of natural disasters.

Liquid phase tandem Knoevenagel-Michael condensation of various aromatic and heteroaromatic aldehydes with barbituric acid or 2-thiobarbituric acid and malononitrile was studied in a one-pot three-component reaction. For the first time, TMDP was employed as a safe and efficient solvent and/or catalyst in the liquid and aqueous ethanol medium, respectively, for the practical and eco-friendly Knoevenagel-Michael condensation. The reactions were carried out by using greener procedures, including a) the use of TMDP as an N-heterocycle organocatalyst in a green medium including water and ethanol (1:1 v/v) at reflux temperature, and b) the use of TMDP as a dual solvent-catalyst at 65 degrees C in the absence of any solvent. High to excellent yields of the desired pyrano[2,3-d] pyrimidinones were obtained under the two earlier mentioned conditions. The current methodologies have advantages, including (a) avoiding hazardous, toxic, volatile, and flammable materials and solvents, (b) avoiding tedious processes, harsh conditions, and multiple steps for the preparation of catalysts, (c) using a less toxic and noncorrosive catalyst, (d) minimizing hazardous waste generation and simple workup process, and (e) high recyclability of TMDP. Another important result of this work is that the TMDP can be a promising alternative for toxic, volatile, and flammable base reagents such as piperidine and triethylamine in liquid phase organic syntheses owing to its unique properties such as being less toxic, nonflammable, and nonvolatile, and having a low melting point, broad liquid range temperature, high thermal stability, and safe handling and storage.

Temperature-enhanced water selectivity of MMMs was demonstrated for the dehydration pervaporation of ethanol solutions. The MMMs synthesized from Polyvinyl alcohol embedded with Poly(2-hydroxyethylmethacrylate)-grafted mesoporous silica nanoparticles revealed a concomitant increasing of the water selectivity and the water flux upon raising feed solution temperature from 30 degrees C to 60 degrees C. This phenomenon is rarely observed in PVA-based MMMs in which the water selectivity usually declines with increasing feed temperature. Remarkably, the temperature enhancing effect was intensified with increasing amount of the grafted PHEMA on MSNs. The enhancement of the water selectivity stems from the superior water absorption selectivity to the water diffusion selectivity because the water absorption by the MMMs is endothermic which gives rise to the favorable absorption as raising feed solution temperature. The incorporation of MSNs-g-PHEMA resulted in improving of both flux and the water selectivity because the mesoporous structure of MSNs-g-PHEMA provides unrestricted and hydrophilic paths for the water permeation.

Developing well-defined iron-based catalysts for olefin metathesis would be a breakthrough achievement in the field not only to replace existing catalysts by inexpensive metals but also to attain a new reactivity taking advantage of the unique electronic structure of the base metals. Here, we present a two-coordinate homoleptic iron complex, Fe(HMTO)(2) [HMTO=O-2,6-(2,4,6-Me3C6H2)(2)C6H3], that is capable of performing ring-opening metathesis polymerization of norbornene to produce highly stereoregular polynorbornene (99 % cis, syndiotactic). The use of heteroleptic Fe(HMTO)(RO) [RO=(CH3)(2)CF3CO, CH3(CF3)(2)CO, or Ph(CF3)(2)CO] prepared in situ significantly increases the polymerization rate while preserving selectivity. The resulting polymers were characterized by H-1 and C-13 NMR spectroscopy and gel-permeation chromatography.

We report aggregation induced emission (AIE) driven polysaccharide polymersomes as fluorescence resonance energy transfer (FRET) nanoprobes to study their intracellular enzyme-responsive delivery by real-time live-cell confocal microscopy bio-imaging techniques. An AIE active tetraphenylethylene (TPE) optical chromophore and plant-based vesicular directing hydrophobic unit were grafted on clinically relevant polysaccharide-dextran via enzyme-cleavable aliphatic ester chemical linkages. The TPE-tagged dextran self-assembled as 180 +/- 20 nm blue-luminescent polymersomes in aqueous medium and exhibited excellent encapsulation capabilities for water soluble Rose Bengal (RB) and water insoluble Nile red (NR) fluorophores. The selective photoexcitation of the TPE chromophore enabled the FRET process between the TPE donor and RB (or NR) acceptor molecule in <50 angstrom Forster distance afforded by the polymersome. The FRET probe was very stable under extracellular conditions and it exclusively underwent lysosomal esterase enzymatic biodegradation at the intracellular compartments to release RB. The enzyme-trigger enabled the FRET probe to function as an extracellular turn-ON -> intracellular turn-Off red-fluorescent signal (Probe-1). In this process, the AIE self-emission was also simultaneously restored on the TPE chromophore (blue-luminescent, Probe-2) followed by the isolation of donor and acceptor in the cytosol. As a result, this new design enabled the visualization of real-time enzyme-responsive delivery by monitoring the dual fluorescent signals from both the polymer host (blue) and encapsulated guest (red) in a single nano-platform. In vitro cytotoxicity studies established that the polymersome probe was non-toxic to cells up to 300 mu g mL(-1). Lyso-tracker staining experiments supported the FRET probe internalization in the lysosomal compartments for enzymatic-biodegradation. Live cell confocal microscopy with selective photo-excitation was used to directly monitor the enzyme-responsive FRET action in human breast cancer MCF 7 and wild-type mouse embryonic fibroblast cell lines (WT-MEFs). It was found that the tailor-made polymersome FRET probe was efficient to deliver the loaded cargo in <3 h in live cells which predicts the usefulness of the probe in biomedical research.

The impact of volatile organic compounds (VOCs) and odor on indoor environment and people has attracted much attention. To reduce this problem of odorous compounds contained in wood panel, this study focused on identifying odorant compounds and exploring the influence of moisture content factors on VOCs and odor emissions. Paper mulberry (Broussonetia papyrifera (L.)Vent.) was investigated using the technology of gas chromatography-mass spectrometry/olfactory (GC-MS/O). Total volatile organic compounds (TVOC) and characteristic odor-active compounds were studied, and the emission of heartwood and sapwood of paper mulberry was compared at the same time. It was found that the main components from heartwood and sapwood were aromatics, alkanes, alkenes, aldehydes ketones, alcohols and esters. Totally, 23 kinds of odor-active compounds were identified from heartwood and sapwood of paper mulberry, among which, aromatics and aldehydes ketones were the main odorant compounds. Seven kinds of key odorant compounds were identified in this process. With the decrease in moisture content, the TVOC and total odor intensity of heartwood and sapwood generally decreased. The moisture content had a great effect on VOC release when the moisture content decreased from 70 to 50% and reduced from fiber saturation point (30%) to air saturation point (10%). The main odor impressions of paper mulberry were aromatic, fresh fruit fragrance, sweet scent and special pungent. In the whole process of moisture content decrease, the TVOC, concentration of odorant and odor intensity of sapwood were higher than that of heartwood.
