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. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Application of 578-58-5

On December 5, 2020, Anito, Dejene Assefa; Wang, Tian-Xiong; Liu, Zhi-Wei; Ding, Xuesong; Han, Bao-Hang published an article.Name: 1,4-Dimethoxybenzene The title of the article was Iminodiacetic acid-functionalized porous polymer for removal of toxic metal ions from water. And the article contained the following:

The design of efficient adsorbent with abundant binding sites for heavy metal ions is crucial for developing innovative materials that will remove pollutant metal ions. The high uptake capacity, kinetics, and affinity towards the toxic metals are the key requirements that the materials under invesigation should accomplish. Here we report the synthesis of iminodiacetic acid-functionalized hypercrosslinked polymer (IDA-HCP) for purification of water polluted by toxic metal ions via coordination of carboxylate and amino active sites on the surface of porous polymer. The obtained porous polymer is stable under harsh conditions and the structural features on the polymer work together to help the removal of Pb(II) with 1138 mg g-1 uptake capacity. In the meanwhile, the IDA-HCP reveals reuseability and very promising capture efficiency not only for Pb2+, but also for Hg2+ and Cd2+ from a mixture of Pb2+, Hg2+, Cd2+, Co2+, Fe3+, Zn2+, Mg2+, and Na+ metal ions. This result gives us confidence that the polymer material can solve the pollution problem caused by various metal ions.

On November 8, 2021, Borys, Andryj M.; Hevia, Eva published an article.HPLC of Formula: 93-04-9 The title of the article was The Anionic Pathway in the Nickel-Catalysed Cross-Coupling of Aryl Ethers. And the article contained the following:

The Ni-catalyzed cross-coupling of aryl ethers is a powerful method to forge new C-C and C-heteroatom bonds. However, the inert C(sp2)-O bond means that a canonical mechanism that relies on the oxidative addition of the aryl ether to a Ni0 center is thermodynamically and kinetically unfavorable, which suggests that alternative mechanisms may be involved. Here, we provide spectroscopic and structural insights into the anionic pathway, which relies on the formation of electron-rich hetero-bimetallic nickelates by adding organometallic nucleophiles to a Ni0 center. Assessing the rich co-complexation chem. between Ni(COD)2 and PhLi has led to the structures and solution-state chem. of a diverse family of catalytically competent lithium nickelates being unveiled. In addition, we demonstrate dramatic solvent and donor effects, which suggest that the cooperative activation of the aryl ether substrate by Ni0-ate complexes plays a key role in the catalytic cycle.

Drogkaris, Vasileios; Northrop, Brian H. published an article in 2020, the title of the article was Discrete boronate ester ladders from the dynamic covalent self-assembly of oligo(phenylene ethynylene) derivatives and phenylenebis(boronic acid).Safety of 1,2-Dimethoxybenzene And the article contains the following content:

Three increasingly π-conjugated covalent organic polygons have been prepared by the dynamic covalent condensation of catechol-based oligo(phenylene ethynylene) derivatives with phenylenebis(boronic acid). The assemblies represent a series of boronate ester “ladders” wherein two electron rich oligo(phenylene ethynylene) “rungs” are bridged by electron deficient aryl boronate ester “rails”, resulting in quasi-two-dimensional oligomers of increasing size. Spectroscopic and computational investigations suggest that the ladders exhibit a greater effective conjugation length than comparable oligo(phenylene ethynylene) compounds not bridged by aryl boronate esters. Different conformations, substitutions, and constitutions of boronate ester ladders are also modeled to gain further insight into their influence on π-conjugation and HOMO-LUMO gaps of isolated one-dimensional vs. bridged, quasi-two-dimensional conjugated organic materials.

On November 17, 2021, Zhai, Binbin; Huang, Rongrong; Tang, Jiaqi; Li, Min; Yang, Jinglun; Wang, Gang; Liu, Kaiqiang; Fang, Yu published an article.Category: ethers-buliding-blocks The title of the article was Film Nanoarchitectonics of Pillar[5]arene for High-Performance Fluorescent Sensing: a Proof-of-Concept Study. And the article contained the following:

Substrates play crucial roles for the sensing performances of fluorescent films owing to their effect on the formation of a fluorescent adlayer. However, no such film has been developed through synthesizing a substrate with a defined structure. We herein report a kind of self-standing, uniform, and thickness tunable pillar[5]arene-based nanofilms to serve as substrates for fabricating fluorescent sensing films. In comparison with a glass plate, the pillar[5]arene-based nanofilms can ensure spatial and electronic isolation of immobilized fluorophores and circumvent aggregation-caused quenching in a film state. For conceptual proof, a formic acid fluorescent sensing film was developed through simple loading of a fluorophore, a 4-azetidine-1,8-naphthalimide derivative of cholesterol (NA-Ch), onto the prepared nanofilm. Sensing performance studies demonstrated that the fluorescent film showed a sensitive, fast, and highly selective response to formic acid in air with a detection limit of lower than 2.8 mg m-3 and a response time of less than 3 s. Moreover, the sensing is fully reversible and highly repeatable. Further studies showed that the film sensor can be used for fast determination of methanol acidity via vapor sampling. Clearly, innovation of substrates with defined structures can be taken as an effective and efficient way to develop new sensing films via combination with known fluorophores.

Wang, Xia; Xing, Yue; Su, Jing; Wang, Changsheng; Wang, Zishi; Yu, Yinghui; Xu, Hongliang; Ma, DongSheng published an article in 2021, the title of the article was Synthesis of two new naphthalene-containing compounds and their bindings to human serum albumin.Related Products of 91-16-7 And the article contains the following content:

Two naphthalene-containing compounds, 4-hydroxy-6,7-dimethoxy-1-(4-(trifluoromethyl)phenyl)-2-naphthoic acid (A) and 4-hydroxy-6,7-dimethoxy-1-phenyl-2-naphthoic acid (B), were prepared by several steps. Their bindings to human serum albumin (HSA) were studied by UV-visible (UV-vis) absorption, fluorescence, synchronous fluorescence, three-dimensional fluorescence, CD (CD) spectroscopies and mol. docking. The crystal data of these compounds show the structure of the compounds The results show that the mechanism of the interaction between compound A and HSA is mixed-quenching (both dynamic and static quenching), while that of compound B and HSA is static quenching. The number of binding sites, binding constants and binding distance (r) were obtained. The interaction processes are spontaneous. A mainly interacts with HSA through typical hydrophobic interaction, and B binds to HSA mainly by the hydrogen bonds and van der Waals forces. The conformation of HSA changes slightly after the addition of the compounds Besides, mol. docking method was used to study the interaction details between the compounds and HSA. This is helpful to understand the absorption and metabolism of these two compounds in the body, and provides a basis for designing naphthalene-containing drugs. Communicated by Ramaswamy H.
