On June 30, 1999, Li, Xiao-Chang; Liu, Yunqi; Liu, Michelle S.; Jen, Alex K.-Y. published an article.Reference of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Synthesis, Properties, and Application of New Luminescent Polymers with Both Hole and Electron Injection Abilities for Light-Emitting Devices. And the article contained the following:

New luminescent polymers that contain both electron-withdrawing cyano groups and electron-rich moieties, triphenylamine (TPA) or tetraphenyldiaminobiphenyl (TPD), were synthesized by Knoevenagel condensation of 1,4-bis(cyanomethyl)-2-[(2-ethylhexyl)oxy]-5-methoxybenzene with the dialdehyde of TPA or TPD, resp. The polymers were characterized by NMR, FT-IR, microanal., GPC, DSC, and TGA. Efficient orange photoluminescence was observed with an absolute quantum efficiency of 48% for the TPA incorporated polymer (TPA-CNPPV). Cyclic voltammetry investigation showed that the polymers presented reversible oxidation and reduction with relatively low potentials, which suggested that the polymers have both good electron and hole injection abilities. We demonstrated an effective approach to synthesize polymers with the triad properties of efficient photoluminescence, good hole injection and high electron-affinity properties, which are highly desirable for application in light-emitting devices. This point was supported by the demonstration of a single layer light-emitting device with a configuration of ITO/TPA-CNPPV/Al, in which good external quantum efficiency (0.1%) and bright luminance of 2100 cd/m2 was achieved. Multilayer LEDs using the polymers as the active layers and different charge injection/transporting layers were also investigated. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Reference of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

Alhamed, Samiyah; Alnakhli, Jawzah; Boadi, William; Beni, Ryan published an article in 2019, the title of the article was Triphenylmethanol conjugates of triptorelin as anti-lipid peroxidation prodrugs.Product Details of 321-28-8 And the article contains the following content:

Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable mols. that the body produces as a reaction to environmental and other pressures. Free radicals may play a role in heart disease, cancer and other diseases. If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function. Free radicals are also known as reactive oxygen species (ROS). In this research, Triptorelin (TRP) conjugates of triphenylmethanol derivatives (TPMs) were synthesized to evaluate their in vitro lipid peroxidation potency. Comparative lipid peroxidation assays between TRP-TPMs conjugates and the corresponding TPMs derivatives were measured using thiobarbituric reactive substance (TBARS) in a dose- and time-dependent manner following the Fenton’s pathway. Overall, TBARS decreased between 20% – 30% for the treated samples of synthesized conjugates compared to their resp. control phys. mixtures These data suggest that TRP-TPMs derivatives can be used to improve the biol. activity of TRP. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Product Details of 321-28-8

On March 15, 2021, Aniceto, Jose P. S.; Zezere, Bruno; Silva, Carlos M. published an article.HPLC of Formula: 578-58-5 The title of the article was Machine learning models for the prediction of diffusivities in supercritical CO2 systems. And the article contained the following:

The mol. diffusion coefficient is fundamental to estimate dispersion coefficients, convective mass transfer coefficients, etc. Since exptl. diffusion data is scarce, there is significant demand for accurate models capable of providing reliable diffusion coefficient estimations In this work we applied machine learning algorithms to develop predictive models to estimate diffusivities of solutes in supercritical carbon dioxide. A database of exptl. data containing 13 properties for 174 binary systems totaling 4917 data points was used in the training of the models. Five machine learning algorithms were evaluated and the results were compared with three commonly used classic models. The best results were found using the Gradient Boosted algorithm which showed an average absolute relative deviation (AARD) of 2.58% (pure prediction). This model has five parameters: temperature, d., solute molar mass, solute critical pressure and solute acentric factor. For the same dataset, the classic Wilke-Chang equation showed AARD of 12.41%. The developed model is provided as command line program. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).HPLC of Formula: 578-58-5

On December 1, 2013, Itoh, Takahito; Fujita, Katsuhito; Inoue, Kentaro; Iwama, Hiroki; Kondoh, Kensaku; Uno, Takahiro; Kubo, Masataka published an article.HPLC of Formula: 929-37-3 The title of the article was Solid polymer electrolytes based on alternating copolymers of vinyl ethers with methoxy oligo(ethyleneoxy)ethyl groups and vinylene carbonate. And the article contained the following:

Alternating copolymers (poly(1a-g-alt-VC)) of vinyl ethers with various methoxy oligo(ethyleneoxy)ethyl groups and vinylene carbonate (VC) were prepared, and the thermal and electrochem. properties of their polymer electrolytes with LiTFSI and interfacial stability between the polymer electrolyte and Li metal electrode were investigated. Tg’s increased linearly with salt contents, and decreased with an increase in the chain length of methoxy oligo(ethyleneoxy)ethyl groups in the vinyl ethers at constant salt concentration The slopes of Tg vs. [Li]/[O] were identical, independent of the polymer structure. The ionic conductivities of the polymer electrolytes increased with increasing the side-chain ethyleneoxy (EO) unit length of the vinyl ether unit in the alternating copolymers, and also their temperature dependences became relatively smaller in the polymer electrolytes having longer EO units in the vinyl ethers. The highest ionic conductivity, 1.2 × 10-4 S/cm at 30°C, was obtained in the alternating copolymer with a side-chain EO unit length of 23.5 in the vinyl ether unit. Ion transport coupled with the segmental motion of the polymer is dominant in these polymer electrolytes. Interfacial resistance increased gradually with contact time, indicative of the formation of passivation films on the Li metal electrode. These polymer electrolytes are thermally stable and have large electrochem. windows of use. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).HPLC of Formula: 929-37-3

On January 21, 2015, Shih, Kuo Sheng; Chen, Chien Chung; Chen, Po-Tsun; Yang, Ya-Wei; White, Jonathon D.; Chang, Yu-Ming; Yang, Arnold Chang-Mou published an article.Related Products of 146370-51-6 The title of the article was Photoluminescence of MEH-PPV Brushes, Pancakes, and Free Molecules in Solutions and Dry States. And the article contained the following:

Photoluminescence (PL) of a conjugated polymer MEH-PPV, poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene], grafted on a silicon wafer with controlled tether spacing was studied to reveal the effects of mol. conformation, chain packing, and mech. stress. In the solvent-swollen state, the PL of the densely grafted polymer (denoted “brushes”) was blue-shifted substantially relative to the lightly grafted (denoted “pancakes”) and free polymers. As solvent evaporated, while for the brushes the changes in PL were insignificant, the PL spectra of the pancakes underwent large blue shifts and exhibited significant efficiency enhancements up to ∼175-fold. The solvent evaporation effects were attributed to mol. deformations resulting from coil contraction on the substrate, which gave rise to conjugation-disruptive kinks (blue shift) and segmental stretching (PL enhancement) in the dried mols. Moreover, heterojunctional quenching was found significantly suppressed by the mech. stresses. Similar behavior was observed in dried free single mols. These results unveil the fundamental role of mech. stresses, not only indirectly through their influence on mol. conformations, but directly via alterations of the excitonic behavior. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Related Products of 146370-51-6
