And the article contained the following:

A new DTBP/Mg(NO3)2-mediated bicyclization cascade of o-arylalkynylanilines with secondary arylphosphine oxides was developed, enabling dual C(sp2)-H functionalization along with the cleavage of the C-N bond. The combination between regioselective P-centered radical-triggered [3 + 2] cyclization and C-centered radical-induced cross-coupling in a 1-pot manner delivered 27 examples of tribenzo[b,e,g]phosphindole oxides with generally high regioselectivity. A reasonable mechanism for forming such products involving radical addition-cyclization cascade is proposed. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Application In Synthesis of 2-((4-Methoxyphenyl)ethynyl)aniline

And the article contained the following:

In order to improve efficiency, processability, and stability, two groups of novel poly(p-phenylene vinylene) (PPV) derivatives (P1-P3 and P4-P6) with hyperbranched structure and containing a nitro substituent were synthesized via a Gilch reaction in different monomer ratios. The properties of the polymers were investigated by using UV-Vis absorption, fluorescence spectroscopy, cyclic voltammetry, and thermogravimetric anal. The result shows that the band gaps of the PPV derivatives with a nitro substituent were decreased and the polymers had higher mol. weights (106), excellent solubility in common organic solvents, good film-forming ability, and better thermal stability. The polymers can be used as an efficient acceptor material in polymeric solar cells. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Related Products of 146370-51-6

Elacqua, Elizabeth; Gregor, Maria published an article in 2019, the title of the article was Poly(arylenevinylene)s through Ring-Opening Metathesis Polymerization of an Unsymmetrical Donor-Acceptor Cyclophane.Recommanded Product: 146370-51-6 And the article contains the following content:

Reported are well-defined donor-acceptor alternating copolymers prepared using ring-opening metathesis polymerization (ROMP). Unsym. cyclophanedienes comprising electron-donating (4-methoxy-1-(2-ethylhexyl)oxy)benzene (MEH) and electron-accepting benzothiadiazole (BT) rings were synthesized from the corresponding [3.3]dithiaparacyclophanes. ROMP of the strained unsym. and “electronically-ambiguous” cyclophanedienes proceeded in a controlled manner in the presence of either Hoveyda-Grubbs II or Grubbs II initiator in wake of both steric and electronic encumbrance. The resulting polymers, comprising alternating BT and MEH-PPV units, are achieved in mol. weights exceeding 20k with D values ranging from 1.1-1.4. The living nature of the polymerization is verified through the formation of rod-coil and rod-rod block copolymers. Our strategy to develop previously unrealized polymers from functional building blocks featuring a locked-in D-A unit is significant in a field striving to achieve well-defined and sequence-specific materials.

On February 17, 2016, Ortiz-Cervantes, Carmen; Flores-Alamo, Marcos; Garcia, Juventino J. published an article.Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline The title of the article was Synthesis of pyrrolidones and quinolines from the known biomass feedstock levulinic acid and amines. And the article contained the following:

A series of N-(alkyl/aryl/aralkyl)-5-methyl-2-pyrrolidones I [R = t-Bu, c-hex, Bn, etc.] was prepared via ruthenium nanoparticles- catalyzed reductive amination of levulinic acid with various amines using formic acid as the hydrogen source. Ruthenium nanoparticles with a mean diameter of cal 3.8 nm were prepared by thermal decomposition of [Ru3(CO)12] in solvent-free conditions. When these reductive thermal reactions were carried out without the catalyst, the pyrrolidons were obtained with low yield and poor selectivity. The reductive amination reaction between levulinic acid and 2-ethynyl aniline surprisingly produced 2-(2,4-dimethylquinolin-3-yl)acetic acid. Furthermore, synthesis of substituted quinolines II [R1 = H, Et; R2 = H, Me, OMe] was achieved through p-toluenesulfonic acid-promoted condensation of levulinic acid and 2-alkynyl anilines. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline

On May 20, 2015, Minar, Norma K.; Docampo, Pablo; Fattakhova-Rohlfing, Dina; Bein, Thomas published an article.SDS of cas: 146370-51-6 The title of the article was Guided in Situ Polymerization of MEH-PPV in Mesoporous Titania Photoanodes. And the article contained the following:

Incorporation of conjugated polymers into porous metal oxide networks is a challenging task, which is being pursued via many different approaches. We have developed the guided in situ polymerization of poly(2-methoxy-5-(2′-ethylhexyloxy)-p-phenylenevinylene) (MEH-PPV) in porous titania films by means of surface functionalization. The controlled polymerization via the Gilch route was induced by an alkoxide base and by increasing the temperature The selected and specially designed surface-functionalizing linker mols. mimic the monomer or its activated form, resp. In this way, we drastically enhanced the amount of MEH-PPV incorporated into the porous titania phase compared to nonfunctionalized samples by a factor of 6. Addnl., photovoltaic measurements were performed. The devices show shunting or series resistance limitations, depending on the surface functionalization prior to in situ polymerization of MEH-PPV. We suggest that the reason for this behavior can be found in the orientation of the grown polymer chains with respect to the titania surface. Therefore, the geometry of the anchoring via the linker mols. is relevant for exploiting the full electronic potential of the conjugated polymer in the resulting hybrid composite. This observation will help to design future synthesis methods for new hybrid materials from conjugated polymers and n-type semiconductors to take full advantage of favorable electronic interactions between the two phases.
