Kucuk, Asuman C.; Matsui, Jun; Miyashita, Tokuji published an article in 2012, the title of the article was Proton-conducting electrolyte film of double-decker-shaped polyhedral silsesquioxane containing covalently bonded phosphonic acid groups.Synthetic Route of 929-37-3 And the article contains the following content:

As described phosphonic-acid-containing double-decker polyhedral silsesquioxane (PHOS-DDSQ) was synthesized and the p conductivity of the PHOS-DDSQ cast film was studied under humid and non-humid conditions. To synthesize PHOS-DDSQ, double-decker-shaped polyhedral silsesquioxane (DDSQ) was reacted with di(ethylene glycol) (DEG) vinyl ether using hydrosilylation reaction to attach 4 DEG units to one DDSQ (4DEG-DDSQ). Subsequently, a phosphate esterification of hydroxyl groups in 4DEG-DDSQ was carried out using POCl3. NMR, XPS, and MALDI-TOF MS spectra and titration measurements revealed that the phosphate esterification connected 2 DEG units to form a crown-ether-like structure. This structure prevents hydrolysis of the phosphate ester bond. PHOS-DDSQ showed high thermal stability, with decomposition temperature exceeding 220°, because of its inorganic DDSQ core. A uniform film of PHOS-DDSQ can be fabricated by drop casting. The cast film showed high p conductivity (0.12 S/cm) under humid conditions, which is comparable to that of a Nafion membrane. Also, the cast film offered good p conductivity under non-humid conditions (3.6 × 10-4 S/cm at 170°). The conductivity and thermal stability indicate that PHOS-DDSQ is a good candidate for use as a p-conductive membrane in hydrated type fuel cells as well as fuel cells operated at intermediate temperatures (100-200°) under non-humid conditions. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Synthetic Route of 929-37-3

Bitenc, J.; Dominko, R. published an article in 2020, the title of the article was Organic compounds as electrodes for rechargeable Mg batteries.Formula: C8H10O2 And the article contains the following content:

Redox-active organic materials were for the first time applied in a Mg bat- tery as a pos. electrode. Electrochem. tests showed some reversible activity with discharge voltages of around 1.4 V vs. Mg/Mg2+. However, it has to be noted that their tests were carried out in Mg electrolytes prepared from Grignard compounds, which means that the presence of nucleophilic species in the final electrolyte solu- tions cannot be excluded. Addnl., the use of copper current collectors could be problematic since it has been demonstrated that copper is prone to corrosion in chloride-containing electrolytes. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On August 31, 2016, Boursalian, Gregory B.; Ham, Won Seok; Mazzotti, Anthony R.; Ritter, Tobias published an article.COA of Formula: C7H7FO The title of the article was Charge-transfer-directed radical substitution enables para-selective C-H functionalization. And the article contained the following:

Efficient C-H functionalization requires selectivity for specific C-H bonds. Progress has been made for directed aromatic substitution reactions to achieve ortho and meta selectivity, but a general strategy for para-selective C-H functionalization has remained elusive. Herein we introduce a previously unappreciated concept that enables nearly complete para selectivity. We propose that radicals with high electron affinity elicit arene-to-radical charge transfer in the transition state of radical addition, which is the factor primarily responsible for high positional selectivity. We demonstrate with a simple theor. tool that the selectivity is predictable and show the utility of the concept through a direct synthesis of aryl piperazines. Our results contradict the notion, widely held by organic chemists, that radical aromatic substitution reactions are inherently unselective. The concept of radical substitution directed by charge transfer could serve as the basis for the development of new, highly selective C-H functionalization reactions. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).COA of Formula: C7H7FO

On March 1, 2022, Yu, Jingxiong; Liu, Fanggang; Deng, Zefeng; Shi, Zaifa; Zhang, Jiangle; Wang, Qiaolin; Yang, Jing; Hu, Haoquan; Qin, Zhengbo; Tang, Zichao published an article.Category: ethers-buliding-blocks The title of the article was Insights into a Low-Rank Naomaohu Coal Structural Information by Multistage Fractions Coupled with LIAD-VUVPI-TOFMS. And the article contained the following:

In-depth insights into the chem. composition and structural information of coal are an effective way to improve the efficiency of coal utilization. Laser-induced acoustic desorption coupling with vacuum UV photoionization time-of-flight mass spectrometry (LIAD-VUVPI-TOFMS) was applied to structural characterization of cyclohexane extracts of low-rank Naomaohu coal. The characterization of four types (12 model compounds) of mixed coal model compounds (three compounds per category)-saturated hydrocarbons, substitute aromatic hydrocarbons, aromatic hydrocarbons, and aromatic heteroatom rings-demonstrated that the approach can provide intact mol. weight information. The cyclohexanone extract (ECYC) was obtained by microwave-assisted extraction and separated into four group components (F1-4) by column chromatog. to achieve component classification and simplify anal. The mol. weight and structure were obtained by LIAD-VUVPI-TOFMS and synchronous fluorescence spectroscopy, combined with microwave-assisted extraction and column chromatog. to sep. product characteristics. Chem. components of a total of 248 species were observed, of which 46 are derived from aliphatic hydrocarbons embedded in the coal skeleton structure, 132 species are derived from aromatic hydrocarbons embedded in the coal skeleton structure, 61 are derived from possible coal skeleton units (compounds have obvious stacking and bonding effects), and 9 could not be determined (aromatic hydrocarbons or a possible coal skeleton structure unit). The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Category: ethers-buliding-blocks
