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 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.

On July 12, 2022, Kleybolte, Moritz E.; Vagin, Sergei I.; Rieger, Bernhard published an article.Application of 146370-51-6 The title of the article was High-Molecular-Weight Bisalkoxy-Substituted Poly(para)phenylenes by Kumada Polymerization. And the article contained the following:

Substituted poly(para)phenylenes (PPPs) are conjugated polymers with an attractive application potential in various fields of materials science. They are synthesized nearly exclusively using catalytic cross-coupling polymerization reactions based on Pd- or Ni-catalysts. Among these synthetic approaches to access alkoxy-substituted PPPs, Kumada catalyst transfer polymerization (KCTP or GRIM polymerization) would offer certain economic advantages over Suzuki-type polymerization as it relies on the utilization of a non-precious metal for catalysis. It also results in less total costs of the utilized reagents, avoiding addnl. preparative steps such as synthesis, isolation, and purification of boronic acid derivatives necessary for the Suzuki reaction. In fact, KCTP is nowadays the state-of-the-art method for the synthesis of polythiophenes. However, the application of KCTP for the synthesis of alkoxy-substituted PPPs leads to polymers with low mol. weights, limiting their practical applicability. Here, we developed a synthesis protocol that resulted in MEH-PPP with a mol. weight of Mn = 133 kg/mol and BHex-PPP with Mn = 153 kg/mol relative to polystyrene, outperforming the previous state of the art by a factor more than 5. Also, a tetra(ethylene glycol)-substituted PPP has been prepared by this procedure, with a mol. weight exceeding the previously reported results for analogous structures. Such mol. weights can be obtained in a reasonable reaction time (5 days) using low concentrations of an N-heterocyclic carbene-coordinated Ni complex. The polymerization kinetics suggested a chain-growth mechanism with a chain transfer step. The latter is caused most likely by a bimol. interaction of the Ni-species at the polymer chain ends. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Application of 146370-51-6

On November 30, 2000, Pan, Jiang-Qing; Chen, Zi-Kuan; Xiao, Yang; Huang, Wei published an article.HPLC of Formula: 146370-51-6 The title of the article was Synthesis and characterization of fully soluble polyphenylenevinylene. And the article contained the following:

Fully soluble poly[2-(2-ethylhexyloxy)-5-methoxy-p-phenylenevinylene] was synthesized by the polymerization of 2-(2-ethylhexyloxy)-5-methoxy-1,4-xylylene dibromide with addition of mol. weight modifiers (chain stopper, free radical scavengers) to a polymerization system containing monomer, catalyst, and solvent. The polymers synthesized in this work were characterized by IR, NMR, and UV-visible spectroscopy, and gel-permeation chromatog. Results show that the weight-average mol. weight of the polymer can be controlled by the addition of chain stopper (benzyl bromide) and radical inhibitor (BHT). The polymerization mechanism in the presence of these additives was also discussed. A dual mechanism involving carbene for the polymerization was proposed.

And the article contained the following:

The synthesis and the chem. phys. characterization of new photoluminescent (PL) chromophores and polymers are reported. Chromophores (oligo-PPV sym. derivatives ending with amino groups) are strong blue emitters with a PL quantum yield of ∼70% in dioxane solution They have been used to prepare polyamides by reaction with aliphatic acyl dichlorides in which emitting and non emitting units are alternated. PL properties of the synthesized polyamides have been evaluated in solution and reveal a strong blue emission (PL quantum yield ∼60%), to increase the solubility of these systems, oligomers have been purposely prepared and then characterized. They show a peculiar white emission when excited in DMF solution; to get insight into this interesting behavior, asym. monoacetylated chromophores have been prepared as model compounds for the chromophoric end groups of the polyamide chains. The emission spectra of these compounds reveal a broad excimeric yellow emission which is responsible, along with the blue emission of the inner chromophoric units, of the overall white emission of the oligomers. © 2009 Wiley Periodicals, Inc.

On April 1, 2008, Karastatiris, Panayiotis; Mikroyannidis, John A.; Spiliopoulos, Ioakim K. published an article.SDS of cas: 146370-51-6 The title of the article was Bipolar poly(p-phenylene vinylene)s bearing electron-donating triphenylamine or carbazole and electron-accepting quinoxaline moieties. And the article contained the following:

Two new poly(phenylenevinylene)s (PPVs) carrying electron-donating triphenylamine or carbazole and electron-deficient quinoxaline units were synthesized and characterized. Their properties were compared with those of PPV containing only quinoxaline unit. The two polymers showed PL maximum at 501-510 in solution and 533-540 in thin film. Because of the presence of electron donor and acceptor units they displayed strong intramol. charge transfer (ICT) effects; hence, low-photoluminescence (PL) quantum yields. The polymers showed reversible electrochem. reduction with electron affinity of 2.75 eV and irreversible oxidation with ionization potential of 5.10-5.24 eV. Single-layer LED of configuration ITO/PEDOT/polymer/Al showed low turn-on voltage at 5 V, but limited brightness of 50-60 cdm-2. The electroluminescence maximum was voltage-tunable varying from 500 to 542 nm.
