On September 1, 2008, Deepa, P.; Jayakannan, M. published an article.Reference of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Polyurethane-oligo(phenylenevinylene) random copolymers: π-conjugated pores, vesicles, and nanospheres via solvent-induced self-organization. And the article contained the following:

We report a new series of polyurethane-oligo(phenylenevinylene) (OPV) random copolymers and their self-assembled nanomaterials such as pores, vesicles, and luminescent spheres. The polymers were synthesized through melt transurethane process by reacting a hydroxyl-functionalized OPV with diurethane monomer and diol under solvent-free and nonisocyanate conditions. The amount of OPV was varied up to 50 mol % in the feed to incorporate various amounts of π-conjugated segments in the polyurethane backbone. The π-conjugated segmented polymers were subjected to solvent induced self-organization in THF or THF+water to produce variety of morphologies ranging from pores (500 nm to 1 μm) to spheres (100 nm to 2 μm). Upon shining 370-nm light, the dark solid nanospheres of the copolymers transformed into blue luminescent nanoballs under fluorescence microscope. The mechanistic aspects of the self-organization process were studied using solution FTIR and photophys. techniques such as absorption and emission to trace the factors which control the morphol. FTIR studies revealed that the hydrogen bonding plays a significant role in the copolymers with lower amount of OPV units. Time resolved fluorescent decay measurements of copolymers revealed that mol. aggregation via π-conjugated segments play a major role in the samples with higher OPV content in the random block polymers. 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

On January 12, 2004, Li, Hongchao; Zhang, Yanguang; Hu, Yufeng; Ma, Dongge; Wang, Lixiang; Jing, Xiabin; Wang, Fosong published an article.Reference of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was Novel soluble N-phenyl-carbazole-containing PPVs for light-emitting devices: Synthesis, electrochemical, optical, and electroluminescent properties. And the article contained the following:

Novel PPV derivatives (PCA8-PV and PCA8-MEHPV) containing N-phenyl-carbazole units on the backbone were successfully synthesized by the Wittig polycondensation of 3,6-bisformyl-N-(4-octyloxy-phenyl)carbazole with the corresponding tri-Bu phosphonium salts in good yields. The newly formed and dominant trans vinylene double bonds were confirmed by FT-IR and NMR spectroscopy. The polymers (with M̅w of 6289 for PCA8-PV and 7387 for PCA8-MEHPV) were soluble in common organic solvents and displayed high thermal stability (Tgs are 110.7°C for PCA8-PV and 92.2°C for PCA8-MEHPV, resp.) because of the incorporation of the N-phenyl-carbazole units. Cyclic voltammetry investigations (onsets: 0.8 V for PCA8-PV and 0.7 V for PCA8-MEHPV) suggested that the polymers possess enhanced hole injection/transport properties, which can be also attributed to the N-phenyl-carbazole units on the backbone. Both the single-layer and the double-layer light-emitting diodes (LEDs) that used the polymers as the active layer emitted a greenish-blue or bluish-green light (the maximum emissions located 494 nm for PCA8-PV and 507 nm for PCA8-MEHPV, resp.). Compared with those of the single-layer devices, the emission efficiencies of the double-layer devices, in which an electron-transporting layer (Alq3) was added, were enhanced by a factor of 10, implying that the better hole-electron balance is achieved because of the incorporation of the electron-transporting layer.

On December 31, 2020, Ye, Qiaoqiao; Yokoyama, Tomoya published an article.Electric Literature of 91-16-7 The title of the article was Revisiting the mechanism of β-O-4 bond cleavage during acidolysis of lignin VII: acidolyses of non-phenolic C6-C2-type model compounds using HBr, HCl and H2SO4, and a proposal on the characteristic action of Br- and Cl-. And the article contained the following:

A non-phenolic C6-C2-type lignin model compound with the β-O-4 bond, 2-(2-methoxyphenoxy)-1-(3,4-dimethoxyphenyl)ethanol (I), was acidolyzed in aqueous 82% 1,4-dioxane containing HBr, HCl, or H2SO4 with a concentration of 0.2 mol/L at 85°C to examine the differences between these acidolyzes. Compound I primarily converted to an enol ether compound, 1-(2-methoxyphenoxy)-2-(3,4-dimethoxyphenyl)ethene (II), via the benzyl cation followed by acidolytic β-O-4 bond cleavage regardless of the acid-type, although the disappearance rates of compound I were remarkably different (HBr > HCl >> H2SO4). Acidolyzes of compound II using these acids under the same conditions showed a similar tendency, but the rate differences were much smaller than in the acidolyzes of compound I. Acidolyzes of the α-methyl-etherified derivative of compound I (I-α-OMe) using these acids under the same conditions suggested that the formation rates of the benzyl cation from compound I-α-OMe (also from compound I) are not largely different between the acidolyzes using these acids, but those of compound II from the benzyl cation are remarkably different. Acidolysis of the α-bromo-substituting derivative of compound I (I-α-Br) using HBr under the same conditions showed a characteristic action of Br in the acidolysis. Br adds to the benzyl cation generated from compound I or I-α-OMe to afford unstable compound I-α-Br, resulting in acceleration of the formation of compound II and of the whole acidolysis reaction. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Electric Literature of 91-16-7

And the article contained the following:

Four new fluorene-based alternating polymers (PFR1-S, PFR2-S, PFR3-S, and PFR4-S) containing different comonomers, i.e., 2,5-bis{2-(4′-bromophenyl)-1-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R1), 2,5-bis{2-(4′-bromophenyl)-2-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R2), 2,5-bis{2-(4′-bromothienyl)-1-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R3), and 2,5-bis{2-(4′-bromothienyl)-2-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R4), were designed, synthesized, and characterized. These polymers were thermally stable and readily soluble in common organic solvents. Single layer LED devices fabricated from these polymers emitted bluish green to pure red light. The color of the light emitted by the homopolymer, poly(9,9-dioctylfluorene-2,7-diyl) (PDOF), can be tuned by incorporating R1, R2, R3, and R4 comonomers, which have narrower band gaps. The absorption and emission maxima of the copolymers varied according to the position of the cyano group in the vinylene unit (α- or β-position) and the type of incorporated aromatic group (thiophene or phenylene). Notably, PFR4-S, prepared from R4 and 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9,9′-dioctylfluorene, showed pure red emission (CIE coordinate values x, y = 0.66 and 0.33, resp.) that is almost identical to the standard red (0.66, 0.34) demanded by the National Television System Committee. PFR3-S also exhibited pure red emission (chromaticity values x, y = 0.63 and 0.38, resp.), and its maximum luminance and maximum external quantum efficiency were approx. 3100 cd/m2 at 6 V and 0.46% at 4 V, resp. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Computed Properties of 146370-51-6
