And the article contained the following:

In this work, efficient non-fullerene organic solar cells are demonstrated based on the environmentally-friendly solvent system. The blend films morphol. from the non-halogenated solvent exhibits more suitable phase separation as the non-halogenated additive is employed. In addition, the additive engineering induces the preferentially oriented self-assembly for the mols., which contributes to better exciton dissociation, enhanced carrier mobility, and balanced charge transport. All these benefits for the additive engineering achieve the power conversion efficiency of the environmentally-friendly solvent system processed non-fullerene organic solar cells up to 4.52% efficiency, which promises the non-halogenated solvent system for eco-friendly and sustainable organic solar cell technol. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).HPLC of Formula: 578-58-5

Buhrmester, Claudia; Chen, Jun; Moshurchak, Lee; Jiang, Junwei; Wang, Richard Liangchen; Dahn, J. R. published an article in 2005, the title of the article was Studies of Aromatic Redox Shuttle Additives for LiFePO4-Based Li-Ion Cells.Safety of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene And the article contains the following content:

Fifty eight aromatic organic mols. were screened as chem. shuttles to provide overcharge protection for LiFePO4/graphite and LiFePO4/Li4/3Ti5/3O4 Li-ion cells. The majority of the mols. were based on methoxybenzene and on dimethoxybenzene with a variety of ligands added to explore their effect. The added ligands affect the redox potential of the mols. through their electron-withdrawing effect and affect the stability of the radical cation. Of all the mols. tested, only 2,5-di-tert-butyl-1,4-dimethoxybenzene shows an appropriate redox potential of 3.9 V vs. Li/Li+ and long-term stability during extended abusive overcharge totaling over 300 cycles of 100% overcharge per cycle. The reasons for the success of this mol. are explored. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Safety of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On March 6, 2020, Dhandabani, Ganesh Kumar; Shih, Chia-Ling; Wang, Jeh-Jeng published an article.Related Products of 157869-15-3 The title of the article was Acid-Promoted Intramolecular Decarbonylative Coupling Reactions of Unstrained Ketones: A Modular Approach to Synthesis of Acridines and Diaryl Ketones. And the article contained the following:

Herein, Lewis acid- or Bronsted acid-promoted intramol. C(sp2)-C(sp2) bond cleavage and a novel C(sp2)-C(sp2) bond-forming cascade reaction to synthesize the acridine motif is reported. The metal-free oxidation of the alkyne motif generated the in situ ketone group extracted via a decarbonylation reaction. The mechanistic studies revealed that the electrophilic N-iodo species triggered key decarbonylation reactions via consecutive dearomatization/aromatization reactions. In addition, this acid-promoted C-C bond activation system with internal alkynes to synthesize bis(heteroaryl) ketones is exploited. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Related Products of 157869-15-3

Sousa, Karlisson Rodrigo de Almeida; Benatto, Leandro; Wouk, Luana; Roman, Lucimara Stolz; Koehler, Marlus published an article in 2020, the title of the article was Effects of non-halogenated solvent on the main properties of a solution-processed polymeric thin film for photovoltaic applications: a computational study.Category: ethers-buliding-blocks And the article contains the following content:

Organic photovoltaic (OPV) devices have reached high power conversion efficiencies, but they are usually processed using halogenated toxic solvents. Hence, before OPV devices can be mass-produced by industrial processing, it would be desirable to replace those solvents with eco-friendly ones. Theor. tools may be then a powerful ally in the search for those new solvents. In order to better understand the mechanisms behind the interaction between solvent and polymer, classical mol. dynamics (MD) calculations were used to produce a thin film of poly(4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl-3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl) (PTB7-Th), processed using two different solvents. PTB7-Th is widely applied as a donor material in OPVs. The first solvent is ortho-dichlorobenzene (o-DCB), which is a highly toxic solvent widely used in lab-scale studies. The second solvent is ortho-methylanisole (o-MA), which is an eco-friendly solvent for organic photovoltaic (OPV) manufacturing Here we use a solvent evaporation protocol to simulate the formation of the PTB7-Th film. We demonstrate that our theor. MD calculations were able to capture some differences in the macroscopic properties of thin films formed by o-DCB or o-MA evaporation We found that the interaction of the halogenated solvent with the polymer tends to break the bonds between the lateral thiophenediyl groups and the main chain. We show that those defects may create traps that can affect the charge transport and also can be responsible for a blue shift in the absorption spectrum. Using the Monte Carlo method, we also verified the influence of the resulting MD morphol. on the mobility of holes. Our theor. results showed good agreement with the exptl. measurements and both demonstrate that o-MA can be used to make polymer thin films without any loss of key properties for the device performance. The findings here highlight the importance of theor. results as a guide to the morphol. optimization of green processed polymeric films.

A conjugated copper(II) catecholate based metal-organic framework (namely Cu-DBC) was prepared using a D2-sym. redox-active ligand in a copper bis(dihydroxy) coordination geometry. The π-d conjugated framework exhibits typical semiconducting behavior with a high elec. conductivity of ca. 1.0 S m-1 at room temperature Benefiting from the good elec. conductivity and the excellent redox reversibility of both ligand and copper centers, Cu-DBC electrode features superior capacitor performances with gravimetric capacitance up to 479 F g-1 at a discharge rate of 0.2 A g-1. Moreover, the sym. solid-state supercapacitor of Cu-DBC exhibits high areal (879 mF cm-2) and volumetric (22 F cm-3) capacitances, as well as good rate capability. These metrics are superior to most reported MOF-based supercapacitors, demonstrating promising applications in energy-storage devices.

On October 27, 2015, Menk, Florian; Mondeshki, Mihail; Dudenko, Dmytro; Shin, Suyong; Schollmeyer, Dieter; Ceyhun, Oliver; Choi, Tae-Lim; Zentel, Rudolf published an article.Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Reactivity Studies of Alkoxy-Substituted [2.2]Paracyclophane-1,9-dienes and Specific Coordination of the Monomer Repeating Unit during ROMP. And the article contained the following:

The polymerization of alkoxy-substituted [2.2]paracyclophane-1,9-dienes via ring-opening metathesis polymerization (ROMP) to obtain soluble poly(p-phenylenevinylene)s is a versatile method due to its living nature which enables the possibility of block copolymerization and end group modification. However, detailed studies on the reactivity behavior and the polymerization process of alkoxy-substituted [2.2]paracyclophane-1,9-dienes have not been reported so far. Herein we present a detailed study on the varying tendencies of the four isomers of dimethoxy-(2-ethylhexyloxy)-[2.2]paracyclophane-1,9-diene to undergo ROMP. Therefore, we carried out polymerization combining all individual isomers with five different metathesis catalysts and collected initiation and propagation kinetics for various combinations. Furthermore, we revealed a specific coordination of the monomer repeating unit to the catalyst during the polymerization process and succeeded to polymerize not only the pseudogeminal isomers but also one of the pseudo-ortho isomers. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On September 26, 2022, Sudhakaran, Swetha; Siddiki, S. M. A. Hakim; Kitiyanan, Boonyarach; Nomura, Kotohiro published an article.Application In Synthesis of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was CaO Catalyzed Transesterification of Ethyl 10-Undecenoate as a Model Reaction for Efficient Conversion of Plant Oils and Their Application to Depolymerization of Aliphatic Polyesters. And the article contained the following:

Transesterification of Et 10-undecenoate (derived from castor oil) with cyclohexanemethanol over a CaO catalyst (prebaked at 300°C) gave undec-10-enoate exclusively (yield 92%, selectivity 95-98%) at 100°C, and the activity increased at 120°C with maintaining the high selectivity (97-98%). The transesterification with other alcs., especially primary alcs. (2-ethyl-1-butanol, 1-hexanol, 3-buten-1-ol, and 10-undecen-1-ol), afforded the corresponding esters with high selectivity, indicating the possibility for application of efficient conversion of plant oils to various fine chems. including the monomer for the synthesis of polyesters. Efficient acid-, base-free depolymerization of aliphatic polyesters, poly(ethylene adipate) and poly(butylene adipate), has been demonstrated in this catalysis by transesterification with ethanol and cyclohexanemethanol, affording corresponding adipates and ethylene glycol or butylene glycol exclusively: the reusability of a CaO catalyst has also been demonstrated. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Application In Synthesis of 2-(2-(Vinyloxy)ethoxy)ethanol
