A new ligand (L), 2-(2,3,6,7-tetramethoxy-9-(pyridin-2-yl)-9,10-dihydroanthracen-10-yl) pyridine, has been designed and synthesized. The anthracene ring in the ligand is curved and cannot form a large π bond conjugated system. Ligands have no fluorescence or other optical properties. When the ligand reacts with cuprous nitrate (CuNO3) to form complex (1), [LCuNO3], the anthracene ring magically straightens, and the maximum deviation of all the atoms on the anthracene ring from the anthracene ring plane is only 0.05873 Å. Complex (1) has a large two-photon absorption cross-sectional area and strong fluorescence properties. The nonlinear absorption of complex (1) (in DMF) was measured by the open-aperture Z-scan technique at a 532 nm wavelength. The results of Z-scan experiments show that complex (1) has remarkable nonlinear optical absorption effects with the two-photon absorption cross-section σ = 5969.78 GM. The ligand (L) and complex (1) all have certain thermal stability and their m.ps. are 169 °C for (L), and 297 °C for (1), resp. Their properties indicate that they have potential applications. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 91-16-7

On September 30, 2020, Alves, A. S.; de Moraes, M. M.; da Camara, C. A. G.; Lucena, M. F. A. published an article.Reference of 2-Methylanisole The title of the article was Chemical Composition of the Essential Oil of Cnidoscolus quercifolius from Brazil. And the article contained the following:

Cnidoscolus quercifolius (syn. Cnidoscolusphyllacanthus) belongs to the family Euphorbiaceae and is found exclusively in the Caatinga. To the best of our knowledge, C. quercifolius has not previously been investigated for the identification of the chemicalconstituents of its essential oils. This paper reports for the first time the chem. composition of essential oils from the leaves,flowers, and bark of C. quercifolius occurring in the Caatinga of Brazil. The essential oils obtained through conventional hydrodistillation of fresh leaves, flowers, and bark of C. quercifoliushad a light yellow color. The yield on a fresh weight basis was 0.01% for leaves, 0.03% for flowers, and 0.01% for bark.The oils were submitted to CG-MS for the determination of the constituents. Thirty-one, thirty, and eighteen compounds wereidentified in the essential oils from leaves, flowers, and bark, resp., accounting for 97.3%, 98.5%, and 81.4% of thetotal oils (Table 1). Diterpene was the predominant class of compounds in the leaf (44.6%) and bark (72.5%) oils, whereas monoterpenespredominated in the flower oil (95.5%). The major constituents identified in the leaf oil were phytol (42.1%), α-terpineol(10.9%), and 11,12-dihydroxyvalencene (7.8%). The major constituents identified in the flower oil were γ-terpinene (20.5%)and β-pinene (9.6%). The diterpenes dehydroabietal (29.9%) and abietadiene (21.4%) were the major constituents identifiedin the bark oil. These results suggest the chem. variability among the essentials oils from different organs of C. quercifolius.

On December 1, 2021, Hyun Park, Sang; Su Jin, In; Woong Jung, Jae published an article.Application of 578-58-5 The title of the article was Green solvent engineering for environment-friendly fabrication of high-performance perovskite solar cells. And the article contained the following:

Antisolvent-assisted crystallization is a common process to fabricate high-performance perovskite solar cells (PSCs). At present, toxic organic solvents such as toluene or chlorobenzene have been used as typical antisolvents to fabricate compact perovskite absorber layer for a device, but their impact to environment or human/animal health has remained a challenge to be resolved for commercialization of PSCs. In this study, we suggest (R)-(+)-limonene and 2-methyltetrahydrofuran as eco-compatible and less-toxic antisolvents for preparing high-quality perovskite absorber layer in the inverted PSCs. The green antisolvents afford smooth, compact, less-defect, and full coverage perovskite films, comparable to the typical halogenated antisolvent-processed perovskite films, delivering a PCE up to 18.04% in CH3NH3PbI3-based device. The green antisolvent also demonstrated promising PCEs of 17.85%, 13.46%, and 10.04% in CH3NH3PbI3, CsPbI2Br, and BA2MA3Pb4I13-based PSCs accompanied with a halogen-free solvent-processed PC61BM layer. This work demonstrates a great potential of green antisolvents as a universal approach in obtaining high-quality perovskite films for fabricating high-efficiency PSCs.

In this article, we show that tribromide heterogenized on the surface of silica-coated magnetic nanoparticles modified with N2,N4,N6-tris(aminomethyl)-1,3,5-triazine-2,4,6-triamine [Fe3O4@SiO2-tris(triazine-triamine)-Br3] is a novel and efficient reusable nanocatalyst for the oxidation of sulfides to sulfoxides and oxidative coupling of thiols to disulfides using hydrogen peroxide as green oxidant. The structure of the as-fabricated Fe3O4@SiO2-tris(triazine-triamine)-Br3 was characterized by a series of spectroscopic techniques including FT-IR spectroscopy, SEM, TEM, EDX, VSM, XRD and TGA techniques. TEM and SEM anal. confirmed that the typical silica shell thickness was assessed to be around 20 nm. Recycling studies revealed that the Fe3O4@SiO2-tris(triazine-triamine)-Br3 could be easily recovered by a simple magnetic separation and recycled at least 6 times without deterioration in catalytic activity.

Pelayo Garcia; Sargent, Edward H.; Park, Taiho published an article.Category: ethers-buliding-blocks The title of the article was Efficient and Stable Colloidal Quantum Dot Solar Cells with a Green-Solvent Hole-Transport Layer. And the article contained the following:

Next-generation solution-processed solar cells will hopefully be processed using green solvents, and will unite high performance with operating stability. Colloidal quantum dot/polymer hybrid solar cells are of interest for their harvest of the visible as well as the near IR; however, today′s best polymer hole-transporting layers (HTLs) rely on processing using hazardous solvents such as chlorobenzene. This stems from the strong polymer-polymer attraction in polymeric p-type materials, which accounts for their limited solubility Here, a new random polymeric HTL (asy-ranPBTBDT) is reported that is soluble in green solvents such as 2-methylanisole without compromising ultimate device power conversion efficiency. The new polymer structure induces a strong π-π stacking face-on orientation and less lateral grain growth compared to control asy-PBTBDT, leading to reduced charge recombination and improved device stability. The resulting device exhibits a power conversion efficiency (PCE) of 13.2% and retains 89% of its initial efficiency after 120 h of continuous device operation at the maximum power point, compared to a PCE of 11.4% and 71% degradation for control devices.
