On September 22, 2011, Murthy, A. V. R.; Goel, Mahima; Patil, Shivprasad; Jayakannan, M. published an article.Computed Properties of 146370-51-6 The title of the article was Probing the Role of Chain Length on the Diffusion Dynamics of π-Conjugated Polymers by Fluorescence Correlation Spectroscopy. And the article contained the following:

We investigate the role of the chain length and mol. weight distribution on the diffusion dynamics of freshly synthesized MEH-PPV polymer chains. For the above purpose, a new technique based on combination of size exclusion chromatog. (SEC) with fluorescence correlation spectroscopy (FCS) is developed to probe the diffusion dynamics of a narrow mol. weight distribution of fractionated samples of 20-500 kDa. The narrow dispersed samples were characterized by absorbance, emission, and time-resolved fluorescence decay techniques. The results revealed that the properties of fractionated samples were almost uniform for a wide range of mol. weights A maximum entropy based method for FCS data anal. is employed to obtain the correct diffusion coefficients of the polymer chains with heterogeneous dynamics. The FCS experiment on the unfractionated broad mol. weight sample is not enough to establish the correlation between the mol. weight of the chains with diffusion dynamics and emphasized the need for relatively monodispersed π-conjugated polymers. FCS results show that higher mol. weight chains diffuse much faster than shorter ones. Atomic force microscopy revealed that 300 kDa polymers produced 130 nm particles, whereas 50 kDa polymer chains formed micrometer size aggregates. At higher mol. weights, the strong chain interactions promote the formation of globular (or tightly packed) particles which diffuse faster in solution The low mol. weight chains experience strong interparticle interaction; as a consequence, the diffusion of chains becomes slower. In the present investigation, we demonstrate the need for the narrow polydisperse sample for establishing the correlation between diffusion dynamics and chain length (or mol. weights) of π-conjugated polymers using a single mol. spectroscopy technique such as FCS. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Computed Properties of 146370-51-6

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

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

And the article contained the following:

Multifunctional stimuli-responsive supramol. polymers have applications in the field of smart materials. Herein, a tri-pillar[5]arene-based multifunctional stimuli-responsive supramol. polymer network gel (SPN-DTG) was successfully constructed. Interestingly, the SPN-DTG shows excellent conductivity and tunable blue aggregation-induced emission (AIE) properties. Meanwhile, a series of metal-ion-coordinated supramol. polymer network gels (MSPNs) were successfully constructed by rationally introducing various metal ions into SPN-DTG. The xerogel powder of SPN-DTG shows excellent separation capacity for the removal of Fe3+, Hg2+, Cu2+, and Co2+ from water. More importantly, the Co2+-coordinated supramol. polymer network gel MSPN-Co shows intriguing thermochromic properties. The color of MSPN-Co could be reversibly controlled between light yellow and dark green by controlling the system temperature In addition, the Fe3+-, Hg2+-, Cu2+-coordinated supramol. polymer network gel MSPNs (Mn+ = Fe3+, Hg2+, Cu2+) show high selectivity and quick fluorescence response for I- and H2PO4-. Therefore, the SPN-DTG has applications in multifunctional smart materials with conductivity, AIE, thermochromism, fluorescence detection, and separation properties. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On February 28, 2020, Lee, Junwoo; Kim, Guan-Woo; Kim, Minjun; Park, Sang Ah; Park, Taiho published an article.Application In Synthesis of 2-Methylanisole The title of the article was Nonaromatic Green-Solvent-Processable, Dopant-Free, and Lead-Capturable Hole Transport Polymers in Perovskite Solar Cells with High Efficiency. And the article contained the following:

With the recent developments in the efficiency of perovskite solar cells (PSCs), diverse functionalities are necessary for next-generation charge-transport layers. Specifically, the hole-transport layer (HTL) in the various synthesized materials modified with functional groups is explored. A novel donor-acceptor type polymer, alkoxy-PTEG, composed of benzo[1,2-b:4,5:b’]dithiophene and tetraethylene glycol (TEG)-substituted 2,1,3-benzothiadiazole is reported. The alkoxy-PTEG exhibits high solubility even in nonaromatic solvents, such as 3-methylcyclohexanone (3-MC), and can prevent possible lead leakage via chelation. The optical and electronic properties of alkoxy-PTEG are thoroughly analyzed. Finally, a dopant-free alkoxy-PTEG device processed with 3-MC exhibits 19.9% efficiency and a device with 2-Me anisole, which is a reported aromatic food additive, exhibits 21.2% efficiency in a tin oxide planar structure. The PSC device shows 88% stability after 30 d at ambient conditions (40-50% relative humidity and room temperature). In addition, NMR reveals that TEG groups can chelate lead ions with moderate strength (Kbinding = 2.76), and this strength is considered to be nondestructive to the perovskite lattice to prevent lead leakage. This is the first report to consider lead leakage and provide solutions to reduce this problem.

A new design strategy for high-performance organic cathode active materials for lithium-ion batteries is presented, which involves the assembly of redox-active organic mols. with a crystalline porous structure using mixed-stacked charge-transfer (CT) complexes. Hexahydroxytriphenylene was used as a donor mol. and 1,4,5,8,9,12-hexaazatriphenylene-2,3,6,7,10,11-hexacarbonitrile as an acceptor mol. to give a new porous CT complex (PCT-1) with a pseudo-hexagonal mixed columnar structure. X-ray diffraction measurements and sorption experiments demonstrated that the intercolumnar spaces in PCT-1 can incorporate various mols. accompanied by lattice expansion. A lithium metal battery containing PCT-1 as a cathode active material exhibited a high capacity of 288 mA h g-1 at 500 mA g-1, and this performance was attributed to a combination of the redox-active units and the porous structure of PCT-1. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Product Details of 91-16-7

On April 10, 2021, Zhang, Lei; Jin, Gan; Ma, Tianlin; Wang, Shi published an article.Application In Synthesis of 1,2-Dimethoxybenzene The title of the article was Ion transport in topological all-solid-state polymer electrolyte improved via graphene-oxide. And the article contained the following:

Designing and constructing novel topol. all-solid-state polymer electrolyte (SPE) matrixes can improve the ionic conducting ability of the prepared SPEs compared with the linear ones. Here, we construct a novel topol. polymer electrolyte matrix using triphenylene as core and block poly(Me methacrylate)-poly(poly[ethylene glycol] Me ether methacrylate) as arm. Specifically, the arm is attached onto the core via sequential atom transfer radical polymerization The mol. weight of the polymers is well controlled via adjusting the inventory rating of monomers, the optimal SPE obtained via solution casting has an ambient temperature ionic conductivity of 3.69 × 10-5 S cm-1, which is higher than typical linear poly(ethylene oxide)-based SPE (usually 10-6-10-8 S cm-1). The electrochem. performance is further improved through adding given contents of graphene-oxide into the SPE. Thus, we believe, through mol. designing and the widely used composite tactics, new class of electrolytes with high-electrochem. performance for all-solid-state Li-ion batteries can be developed.

On August 31, 2006, Lin, King-Fu; Fan, Yang-Liang; Chow, Hsuan-Liang published an article.Category: ethers-buliding-blocks The title of the article was Origin of the methylene bonds in poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] prepared according to Gilch’s method: novel applications. And the article contained the following:

Impurities containing methylene bridges between 2-((2′-ethylhexyl)oxy)-5-methoxy-benzene mols. are inevitably formed during the synthesis of 1,4-bis(chloromethyl)-2-((2′-ethylhexyl)oxy)-5-methoxy-benzene, the monomer used in the preparation of poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] (MEH-PPV), but they can be removed by double recrystallization of the monomer prior to polymerization When impurities containing methylene bridges participate in a Gilch polymerization, the methylene bonds formed in the main chains are prone to break at 200 °C, i.e., at least 150 °C below the major degradation temperature of defect-free MEH-PPV. Interestingly, the thermal treatment used to break the methylene bonds bonds present reduces the chain aggregation of MEH-PPV during film formation and induces its blends with poly(2,3-diphenyl-5-octyl-p-phenylene-vinylene) (DPO-PPV) to form a morphol. similar to that of block copolymers. Both significantly enhance the luminescence properties. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Category: ethers-buliding-blocks

On July 31, 2020, An, Kang; Zhong, Wenkai; Ying, Lei published an article.Safety of 2-Methylanisole The title of the article was Enhanced performance of P3HT-based non-fullerene polymer solar cells by optimizing film morphology using non-halogenated solvent. And the article contained the following:

Increasing research interests have been paid to developing efficient polymer solar cells by using integrating non-fullerene acceptors with poly (3-hexylthiophene) (P3HT), owing to the low-cost, promising performance and excellent stability. Here we systematically studied how processing solvents influence the overall performances of polymer solar cells using P3HT as the electron donor. It is very interesting to note that the devices processed with the non-halogenated solvent, 2-methylanisole in presence of 1-methylnaphthalene as solvent additive, exhibit reduced bimol. and trap-assisted monomol. recombination, facile charge extraction and enhanced charge carrier mobilities. Careful morphol. investigation reveals that the optimizing crystallites, phase purity as well as nanofibrous structure is effective to the enhancement of charge generation and transport. It is also worth noting that these P3HT:O-IDTBR based devices processed with these non-halogenated solvents exhibitean impressive power conversion efficiency of 7.1% with a high fill factor of 75.09% on a device area of 0.05 cm2, and the efficiency remained 6.89% even in a device with large active layer area of 1 cm2, while also showing promising thermal stability. This study provides a new scope of processing P3HT based polymer solar cells by using non-halogenated solvents, which is compatible and has great promise for future applications.
