On April 15, 2014, Ravnsbaek, Jens B.; Swager, Timothy M. published an article.Product Details of 146370-51-6 The title of the article was Mechanochemical Synthesis of Poly(phenylene vinylenes). And the article contained the following:

We report a simple, rapid, and solvent-free methodol. for solid-state polymerizations yielding poly(phenylene vinylenes) (PPVs) promoted by ball-milling. This solid-state Gilch polymerization method produces PPVs in as little as five minutes of milling. Detailed investigations of the parameter space governing the solid-state polymerization, i.e., milling time, base strength, solid-state dilution, milling frequency, and size of milling balls, revealed that polymerization by ball-milling is a rapid process achieving mol. number average weights of up to 40 kDa in up to 70% yield. To explore the scope, a solid-state polymerization via the dithiocarbamate precursor route is explored.

Shankar, Jaya Seeli; Ashok Kumar, Sangeetha; Periyasamy, Bhuvana K.; Nayak, Sanjay K. published an article in 2019, the title of the article was Studies on Optical Characteristics of Multicolor Emitting MEH-PPV/ZnO Hybrid Nanocomposite.Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene And the article contains the following content:

The present work endeavors towards the scientific study on influence of ZnO nanoparticles on the optical characteristics of Poly [2 Methoxy (5, 2′ Ethylhexyloxy)-P-Phenylenevinylene] (MEH-PPV), a light emitting polymer. Hybrid nanocomposites of MEH-PPV were prepared by dispersing ZnO nanorods at loading concentrations of 1 weight % and 3 weight %. The structural characteristics of the hybrid composites were investigated using FTIR spectroscopy and X-ray diffraction. The UV absorption spectra and Photoluminescence emission spectra were analyzed in order to study the optical characteristics of nanocomposite. The optical constants were determined and the suitability of the composites for light emission was analyzed. The incorporation of ZnO nanorods facilitates the shift in emission wavelength and witnesses the color tuning ability and multicolor emission from the composite. 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 18, 1999, Ahn, Taek; Jang, Min Sik; Shim, Hong-Ku; Hwang, Do-Hoon; Zyung, Taehyoung published an article.Related Products of 146370-51-6 The title of the article was Blue Electroluminescent Polymers: Control of Conjugation Length by Kink Linkages and Substituents in the Poly(p-phenylenevinylene)-Related Copolymers. And the article contained the following:

Poly[o(m,p)-phenylenevinylene-alt-2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene], o(m,p)-PMEH-PPV, and poly[o(m,p)-phenylenevinylene-alt-2,5-bis(trimethylsilyl)-p-phenylenevinylene], o(m,p)-PBTMS-PPV, of varying effective conjugation lengths were synthesized by the well-known Wittig condensation polymerization between the appropriate diphosphonium salts and the dialdehyde monomers such as terephthaldicarboxaldehyde, isophthalaldehyde, and phthalic dicarboxaldehyde. The conjugation lengths of the polymers were controlled by substituents and kink (ortho and meta) linkages. The resulting polymers were highly soluble in common organic solvents. The synthesized polymers showed UV-visible absorbance and photoluminescence (PL) in the ranges of 330-430 nm and 440-550 nm, resp. The maximum emission peak of p-PMEH-PPV was blue shifted about 30 nm compared to that of MEH-PPV, which is due to an unsubstituted phenylene unit. In addition, o-PMEH-PPV and m-PMEH-PPV showed PL emission maximum peaks at 500 and 490 nm, resp., because ortho and meta linkage of the o(m)-PMEH-PPV reduced π-conjugation lengths. The trimethylsilyl substituent has no electron donating effect; therefore, the PL maximum of p-PBTMS-PPV was far more blue shifted (to 485 nm). Consequently, maximum PL wavelengths for o-PBTMS-PPV and m-PBTMS-PPV appeared around 470 and 440 nm, resp. A single-layer light-emitting diode device was fabricated which has a simple ITO (indium-tin oxide)/polymer/Al configuration. The threshold bias of trimethylsilyl-substituted o(m,p)-PBTMS-PPV was in the range of 8-9 V. As in the photoluminescence spectra, the dramatic change of emission color was also shown in electroluminescence spectra of p-PMEH-PPV, p-PBTMS-PPV, and o-PBTMS-PPV when the operating voltage was about 8-9 V. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Related Products of 146370-51-6

And the article contained the following:

A series of new polymers with conjugated poly(p-phenylene vinylene) units and non-conjugated poly(p-xylylene) units containing vinyl and carboxyl groups were synthesized. The monodisperse CdSe/ZnS nanocrystals with a red light emission were prepared by using the phosphine-free precursors. A novel fluorescent polymer and 5-(2-methacryloylethyloxymethyl)-8-quinolinol were dispersed in vinyl monomers containing CdSe/ZnS NCs to successfully fabricate transparent bulk nanocomposites by in situ polymerization The 5-(2-methacryloylethyloxymethyl)-8-quinolinol mols. can be coordinated to the surface of CdSe/ZnS nanocrystals to form a metalloquinolate with green light emission at about 500 nm, while the red light emission of nanocrystals remained after the polymerization process. The efficient white light emitting polymer nanocomposites with color coordinates (0.32, 0.34) can be obtained when the weight ratio of nanocrystals to 5-(2-methacryloylethyloxymethyl)-8-quinolinol is 10:1. A charge transfer from the photoexcited metalloquinolates to the nanocrystals was observed in the system.

O’Shea, Riley; Wong, Wallace W. H. published an article in 2020, the title of the article was Simple improvements to Gilch synthesis and molecular weight modulation of MEH-PPV.Safety of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene And the article contains the following content:

The solvent and temperature used in the Gilch synthesis of poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) were varied to achieve an improved set of reaction conditions. A range of mol. weights from 20 to 500 kg mol-1 were obtained in moderate to near-quant. yields. The best conditions for producing low mol. weight MEH-PPV (32 kg mol-1, 97% yield) was to use n-pentane as the reaction solvent at 25°C. For high mol. weight (397 kg mol-1, 65% yield), toluene at 55°C gave the best result. The photophys. properties for all MEH-PPV samples were examined and no significant variation was found between samples obtained under different polymerization conditions.

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

And the article contained the following:

A series of electroluminescent polymers was prepared, which incorporates segments of 2,5-dicyano-1,4-phenylenevinylene (DCN-PV) into the backbone of poly(2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylene vinylene) (MEH-PPV). The copolymers have optical properties similar to those of MEH-PPV. The oxidation potential of the copolymers is slightly larger than that of MEH-PPV. The copolymers exhibit pre-reduction processes, beginning at about -0.9 V (vs. SCE), before the main reduction processes. The pre-reduction feature promotes electron injection, consequently, it improves electroluminescence (EL) performance. The improved EL performance of the copolymers in comparison with MEH-PPV was demonstrated by a single-layer copolymer as emitter layer in a light-emitting diode (PLED) test device.

On July 8, 2013, Khoshkhoo, Mahdi Samadi; Taromi, Faramarz Afshar; Kowsari, Elaheh; Shalamzari, Elham Khodabakhshi published an article.Application of 146370-51-6 The title of the article was Contribution of chromophores with different numbers of repeat units to overall emission of MEH-PPV: An experimental and simulation study. And the article contained the following:

In the present study, poly[1-methoxy-4-(2′-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) was synthesized, modified and characterized by FTIR, NMR, GPC, UV/vis absorption, fluorescence, and mass spectroscopy. The effective conjugation length was controlled by introducing phys. and chem. defects into the chain backbone. It was observed that absorption and emission spectra of polymer chains were blue-shifted by importing structural deficiencies. Chem. defects were introduced by controlled oxidation of vinylene double bonds using m-chloroperbenzoic acid and phys. defects were induced by tuning polymer-solvent interactions (varying solvent quality). It was shown for the first time that the recorded fluorescence spectrum of MEH-PPV can be reconstructed using the emission data of oligomeric constituents and the contribution of chromophores with different numbers of repeat units to overall emission can be quantified. The effect of excitation energy on the emission pattern was also investigated. It was shown that the emission contribution of shorter chromophores to overall emission is detectable using high excitation energies. Finally, atomistic mol. dynamic (MD) simulation was used to investigate the polymer chain conformation in methanol and chloroform. The results obtained from torsional angles studies confirmed the presence of a great number of induced phys. defects in the backbone and, hence, a collapsed conformation of polymer chains in methanol. Evaluations of phys. defects along the chain proposed the average number of coplanar Ph rings of ∼5 and 14 for polymer chains in methanol and chloroform resp. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Application of 146370-51-6
