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.

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
