Kiliclar, Huseyin Cem; Altinkok, Cagatay; Yilmaz, Gorkem; Yagci, Yusuf published an article in 2021, the title of the article was Visible light induced step-growth polymerization by electrophilic aromatic substitution reactions.Reference of 1,4-Dimethoxybenzene And the article contains the following content:

A novel visible light induced step-growth polymerization to form poly(phenylene methylene) by electrophilic aromatic substitution reactions is described. The effect of different nucleophilic aromatic mols. on polymerization has been investigated. The possibility of combining step-growth polymerization with conventional free radical and free radical promoted cationic polymerizations through photoinduced chain-end activation has been demonstrated. Highly fluorescent fibers of the resulting block copolymers were obtained using the electrospinning technique. The versatile photoinduced step-growth polymerization process reported herein paves the way for a new generation of polycondensates and their combination with chain polymers that cannot be obtained by conventional methods.

On December 22, 2021, Rivero-Crespo, Miguel A.; Toupalas, Georgios; Morandi, Bill published an article.Category: ethers-buliding-blocks The title of the article was Preparation of Recyclable and Versatile Porous Poly(aryl thioether)s by Reversible Pd-Catalyzed C-S/C-S Metathesis. And the article contained the following:

Porous organic materials (polymers and COFs) have shown a number of promising properties; however, the lability of their linkages often limits their robustness and can hamper downstream industrial application. Inspired by the outstanding chem., mech. and thermal resistance of the 1D polymer polyphenylene sulfide (PPS), we have designed a new family of porous poly arylthioethers, synthesized via a mild Pd-catalyzed C-S/C-S metathesis-based method, that merges the attractive features common to porous polymers and PPS in a single material. In addition, the method is highly modular, allowing to easily introduce application-oriented functionalities in the materials for a series of environmentally relevant applications including metal capture, metal sensing and heterogeneous catalysis. Moreover, despite their extreme chem. resistance, the polymers can be easily recycled to recover the original monomers, offering an attractive perspective for their sustainable use. In a broader context, these results clearly demonstrate the untapped potential of emerging single-bond metathesis reactions in the preparation of new, recyclable materials. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Category: ethers-buliding-blocks

And the article contained the following:

A new conjugated polymer, poly{[1′,4′-bis-(thienyl-vinyl)]-2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene-vinylene} (PTVMEH-PPV) was synthesized via Grignard polymerization The polymer is soluble in common organic solvents such as chloroform and THF, and possesses adequate thermal stability (Td > 246 °C). The absorption spectrum of PTVMEH-PPV film shows a broader absorption peak covering the wavelength range from 380 nm to 620 nm, which is red-shifted and broadened in comparison with that of MEH-PPV. The onset oxidation potential of the polymer is 0.12 V vs. Ag/Ag+, ca. 0.2 V lower than that of MEH-PPV. The band gap of the polymer measured by cyclic voltammetry is 1.82 eV, which basically agrees with that obtained from the onset wavelength of the absorption spectra. Polymer solar cell was fabricated based on the blend of PTVMEH-PPV and PCBM with a weight ratio of 1:1. The device shows the maximum external quantum efficiency of 14% at ca. 520 Nm, an open circuit voltage of 0.67 V and a power conversion efficiency of 0.32% under the illumination of AM1.5, 80 mW/cm2.

On October 31, 2006, Yang, Yong; Qiao, Juan; Li, Yinkui; Qiu, Yong published an article.Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Ultrasonic synthesis of poly[2-methoxy-5-(2′-ethylhexyloxy)-p-phenylenevinylene]. And the article contained the following:

Poly[2-methoxy-5-(2′-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) is a typical example of solution processable conjugated polymers for polymeric light emitting diodes application, which shows good solubility in common organic solvents. However, gelation or micro-gelation always occurs during the polymerization process. Herein, we report the synthesis of fully soluble MEH-PPV by ultrasonic irradiation method. The raw material was 4-methoxyphenol, and ultrasonic irradiation method was used in the etherification, bromomethylation and polymerization The polymer is prepared from the bis-bromomethyl monomer through the Gilch route. Compared with the conventional mech. stirring, ultrasonic irradiation method has shown great advantages with respect to the shorter reaction time, lower reaction temperature, higher yields and higher mol. weight (Mn) of MEH-PPV. The optimized reaction conditions including reaction solvent, temperature, and time, were determined for the related etherification, bromomethylation and polymerization with ultrasonic method. Especially, using ultrasonic method, the gelation in the polymerization had been overcome. MEH-PPV obtained was fully soluble in THF and chloroform and no gel or micro-gel existed. The structures of the intermediate products and MEH-PPV were determined by IR and 1H-NMR. It was found the MEH-PPV synthesized by ultrasonic irradiation processes had higher luminescence quantum efficiency than that by mech. stirring. 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 June 30, 2008, Wang, Hualin; Sun, Yueming; Qi, Zhengjian; Jiang, Wei; Song, Kunzhong; Li, Dayan published an article.Electric Literature of 146370-51-6 The title of the article was Synthesis and optical properties of an alternating copolymer composed of MEHPV and 1,3,4-oxadiazole. And the article contained the following:

A poly (p-phenylenevinylene) (PPV) alternating copolymer, poly [(2, 5-diphenylene-1, 3, 4-oxadiazole) 44′ – vinylene-alt-2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (oxa-MEHPV), is synthesized by Heck coupling reaction and characterized with UV-vis, Fourier transform IR (FT-IR), 1H-NMR and photoluminescence (PL) spectroscopy. oxa-MEHPV possesses an outstanding thermal stability and shows excellent solubility in common organic solvents such as dichloromethane, chloroform, toluene, and tetrahydrofuran(THF). The introduction of the electron-deficient 1, 3, 4-oxadiazole units into the MEH-PPV backbone also increases the electron affinities of the conjugated segment, which leads to the blue-shift of the maximum absorption wavelength and makes the polymer have a high optical band-gap energy, good electron-transporting stability and high PL quantum yield.

On May 15, 2009, Li, Shengbiao; Zhao, Ping; Huang, Yanqin; Li, Tingcheng; Tang, Chao; Zhu, Rui; Zhao, Lei; Fan, Quli; Huang, Shiqiang; Xu, Zushun; Huang, Wei published an article.SDS of cas: 146370-51-6 The title of the article was Poly-(p-phenylene vinylenes) with pendent 2,4-difluorophenyl and fluorenyl moieties: Synthesis, characterization, and device performance. And the article contained the following:

To improve efficiency, processability, and stability, three novel poly(p-phenylenevinylenes) (PPVs) derivatives (Pa, Pb, and Pc) with pendent 2,4-difluorophenyl and fluorenyl moieties were synthesized via Gilch reaction. Their structures were characterized by 1H NMR, 13C NMR, and ELEM. ANAL. Compared with those of PPV and MEH-PPV, the absolute quantum efficiencies of these polymers showed remarkable improvement (measured at 38.7, 37.2, and 20.3%, resp.), which can be attributed to the presence of twisted multiaryl segments and fluorine atoms. TGA revealed that the inflection temperatures of their thermal decomposition curves were above 400°. Double-layered electroluminescent devices with these polymers as light-emitting layers [ITO/PEDOT:PSS/Polymer/Ba/Al] showed peak emissions at 493/515, 503, and 600 nm and maximum luminance of 2700, 450, and 4700 cd/m2 for Pa, Pb, and Pc, resp., with onset voltages of ∼4 V. © 2009 Wiley Periodicals, Inc.
