Coulomb, Julien; Certal, Victor; Larraufie, Marie-Helene; Ollivier, Cyril; Corbet, Jean-Pierre; Mignani, Gerard; Fensterbank, Louis; Lacote, Emmanuel; Malacria, Max published an article in 2009, the title of the article was Intramolecular Homolytic Substitution of Sulfinates and Sulfinamides.Formula: C8H10BrNO And the article contains the following content:

A general and efficient method for the synthesis of cyclic sulfinates and sulfinamides based on intramol. homolytic substitution (SHi) at the sulfur atom by aryl or alkyl radicals is described. Both alkyl and benzofused compounds can be accessed directly from easily prepared acyclic precursors. Enantiomerically enriched sulfur-based heterocycles were formed through an SHi process with inversion of configuration at the sulfur atom. Cyclization of prochiral radicals proceeded with varying stereochem. outcomes, depending on the size of the incoming radical. 2-Pyridyl and 2-quinolyl radicals led to biaryl compounds, which result from attack onto the ortho position of the arylsulfinate rather than a thiophilic substitution. The experimental process involved the reaction of (2-Bromo-5-methoxyphenyl)methanamine(cas: 887581-09-1).Formula: C8H10BrNO

On April 13, 2004, Kim, Yun-Hi; Ahn, Jun-Hwan; Shin, Dong-Cheol; Kwon, Soon-Ki published an article.HPLC of Formula: 146370-51-6 The title of the article was Synthesis and characterization of poly(terphenylenevinylene) derivatives containing alkoxy substituents and (or) phenyl pendant group. And the article contained the following:

The blue electroluminescent polymers, poly(terphenylenevinylene) derivatives that have advantages of PPP and PPV, were prepared by Suzuki coupling reaction. The structure and properties of the polymers were analyzed by various spectroscopic methods. Poly(MHTPPV) and poly(TPPV) with Ph pendant group in a vinyl bridge showed blue shifted absorption spectra, large band gap and enhanced thermal stability as compared with that of poly(MHTPV). The PL spectra of the films of the polymers showed maximum peaks at 450-460 nm, which are pure blue emissions. The blue electroluminescence (λmax=450-460 nm) was obtained with the turn on voltage of 8-10 V, when the simple light-emitting diodes of ITO/polymer/Al were fabricated. The excimer emission due to interchain interaction was reduced by the introduction of substituents into the vinyl bridge and (or) the main chain. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).HPLC of Formula: 146370-51-6

On May 31, 2021, Ashok Kumar, Sangeetha; Gouthaman, Siddan; Shankar, Jaya Seeli; Periyasamy, Bhuvana K.; Nayak, Sanjay K. published an article.Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Stable and color tunable MEH-PPV/PMMA polymer blends for light-emitting applications. And the article contained the following:

Light Emitting Polymers (LEPs) have gained attention in optoelectronics. However, stability and regulation of emission color remain a challenge. This study aims to overcome the challenge by formulating a Polymer Blend (PB) which consists of a LEP – poly [2-methoxy,5-(2-ethylhexyloxy)1,4-phynylenevinylene (MEH-PPV) and a non-conjugated polymer – poly(Me methacrylate) (PMMA). A simple approach of in situ polymerization of the non-conjugated polymer in the MEH-PPV solution leads to alteration of size of the MEH-PPV polymer chain and modified the emission color from red-orange to bluish-green. The barrier properties of PMMA improve the stability of PB in an ambient environment with unnoticeable luminescence loss. This type of PB shall find application in Organic Light-Emitting Devices. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On March 8, 2007, Jin, Youngeup; Jee, Jaesung; Kim, Kwanghyun; Kim, Jinwoo; Song, Suhee; Park, Sung Heum; Lee, Kwanghee; Suh, Hongsuk published an article.SDS of cas: 146370-51-6 The title of the article was Synthesis and electroluminescent properties of copolymers based on PPV with fluoro groups in vinylene units. And the article contained the following:

Electroluminescent copolymers with fluoro groups on vinylene units, poly(2-ethylhexyloxy-5-methoxy-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (MEH-PPV-co-DMOS-PPDFV) and poly(2-dimethyloctylsilyl-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (DMOS-PPV-co-DMOS-PPDFV), were synthesized by the Gilch polymerization route. The fluoro groups were introduced on vinylene units to increase the electron affinity of the copolymers. In both copolymers, the band gap increased with higher ratio of DMOS-PPDFV. As compared to the photoluminescence (PL) spectra in solution, the PL spectra in solid state and EL spectra of both copolymers showed red shift and broad peaks caused by aggregation. The LEDs fabricated using MEH-PPV-co-DMOS-PPDFVs emit light with maximum at around 538-577 nm. By adjusting the feed ratio of DMOS-PPDFV in the copolymer, the emission colors were tuned from orange yellow to green. The DMOS-PPV-co-DMOS-PPDFV showed maximum electroluminescence (EL) peaks at about 514-543 nm. The DMOS-PPV-co-DMOS-PPDFV with 1:9 feed ratio showed the highest luminescence efficiency of 1.31 lm/W.

On September 30, 1996, Cumming, W.; Gaudiana, R. A.; Hutchinson, K.; Kolb, E.; Ingwall, R.; Mehta, P.; Minns, R. A.; Petersen, C. P.; Waldman, D. published an article.Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Control of chromophore length in electroluminescent polymers. Part II. Mainchain polymers. And the article contained the following:

Electroluminescence emission has been demonstrated in mainchain polyesters and a structurally analogous polyamide. High-mol.-weight polyesters were synthesized by condensation of a dihydroxy-functionalized, substituted, phenylene vinylene analog, e.g., the lumophore, with a variety of dicarboxylic acid chlorides. The structure and hence the conjugation length of the emitting comonomer was predetermined prior to polymerization Since the diacid moieties did not contribute to the conjugation length and hence the emission wavelength, the structure of the diacid was determined on the basis of its ease of synthesis, reactivity, and solubilizing ability in the final polymer. In each of the polyesters, the electroluminescence wavelength of light-emitting diodes made from these polymers was similar to their photoluminescence emission spectrum in solution and the solid state at room temperature The emission wavelengths ranged from blue to green. The polyamide exhibits a very broad-band, nearly white electroluminescence. Diodes made from these polymers typically have external efficiencies ≤ 0.003% with low turn-on voltages, e.g., 6-20 V. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On May 1, 2009, Wild, Andreas; Egbe, Daniel A. M.; Birckner, Eckhard; Cimrova, Vera; Baumann, Reinhard; Grummt, Ulrich-Walter; Schubert, Ulrich S. published an article.Computed Properties of 146370-51-6 The title of the article was Anthracene- and thiophene-containing MEH-PPE-PPVs: Synthesis and study of the effect of the aromatic ring position on the photophysical and electrochemical properties. And the article contained the following:

This contribution reports on the synthesis and characterization of thiophene- (P1, P2, and P3) and anthracene- (P4 and P5) containing PPE-PPV [poly(phenylene-ethynylene)-poly(phenylenevinylene)] copolymers. The thermostable, soluble and film-forming polymers were fully characterized by NMR, IR and elemental anal.; they exhibit high molar masses with polydispersity indexes below 2.5. The position of the thiophene in the polymeric backbone has insignificant influence on the spectroscopic properties of the polymers. In contrast, the anthracene-containing polymers reveal position dependent optical properties. A constant bathochromic shift of 50 nm was observed going from P4, where anthracene is surrounded by two double bonds, to P5, where anthracene is at the bridge between a triple bond and a double bond, as well as from P5 to P6 where anthracene is surrounded by two triple bonds. This correlates to the decrease of the observed anthracene band around 255 nm going from P4 through P5 to P6, amounting to the degree of contribution of the anthracene unit to the main chain conjugation. The phenomenon known as CN-PPV effect was observed in the case of P4 [Φf (solution) = 3%, Φf (solid) = 13%]. Electrochem. studies carried out under absolute inert conditions revealed lower electrochem. band gap energies, Egec, than Egopt. © 2009 Wiley Periodicals, Inc.
