A general intermol. reductive Heck reaction of organohalides with both terminal and internal unactivated aliphatic alkenes has been first realized in high yield with complete anti-Markovnikov selectivity. The challenging vinyl bromides, aryl chlorides, and polysubstituted internal alkenes were first applied. More than 100 remote carbofunctionalized alkyl carboxylic acid derivatives were rapidly synthesized from easily accessible starting materials. The synthesis of drug mols. has further demonstrated the wide synthetic utility of this scalable strategy. Preliminary mechanistic studies are consistent with the proposed catalytic cycle.

Alaasar, Mohamed; Darweesh, Ahmed F.; Cai, Xiaoqian; Liu, Feng; Tschierske, Carsten published the artcile< Mirror Symmetry Breaking and Network Formation in Achiral Polycatenars with Thioether Tail>, Recommanded Product: 5-Bromo-2,2′-bithiophene, the main research area is alkylsulfanylbenzoyl oxyphenyl dithienylphenyl trialkoxybenzoate preparation thermal stability; bithophene; chirality; cubic phases; liquid crystals; mirror symmetry breaking; soft matter.

The design and mol. self-assembly of two series of rod-like achiral polycatenar mols. derived from a π-conjugated 5,5′-diphenyl-2,2′-bithiophene core with a fork-like triple alkoxylated end and a variable single alkylthio chain at the other end was discussed. In both series of liquid crystalline materials, differed in the chain length at the trialkoxylated end, helical self-assembly of the π-conjugated rods in networks occurs, leading to wide temperature ranges (>200 K) of bicontinuous cubic network phases, in some cases it stayed stable even around ambient temperatures The achiral bicontinuous cubic Ia3d phase (gyroid) was replaced upon alkylthio chain elongation by a spontaneous mirror symmetry broken bicontinuous cubic phase (I23) and a chiral isotropic liquid phase (Iso1[*]). Further chain elongation resulted in removing the I23 phase and the re-appearance of the Ia3d phase with different pitch lengths. In the second series an addnl. tetragonal phase separated the two cubic phase types.

Kubota, Koji; Endo, Tsubura; Uesugi, Minami; Hayashi, Yuta; Ito, Hajime published the artcile< Solid-State C-N Cross-Coupling Reactions with Carbazoles as Nitrogen Nucleophiles Using Mechanochemistry>, Product Details of C8H5BrS2, the main research area is arylcarbazole preparation; aryl halide arylcarbazole solid state cross coupling palladium catalyst; ball milling; carbazole; cross-coupling; mechanochemistry; solid-state reaction.

The palladium-catalyzed solid-state C-N cross-coupling of carbazoles with aryl halides via a high-temperature ball-milling technique was reported. This reaction allowed simple, fast, and efficient synthesis of N-arylcarbazole derivatives I [R1 = 4-MePh, 2-naphthyl, 9-pyrenyl, etc.; R2 = H, t-Bu, Ph, etc.] in good to excellent yields without the use of large amounts of organic solvents in air. Importantly, the developed solid-state coupling approach enabled the cross-coupling of poorly soluble aryl halides with large polyaromatic structures that are barely reactive under conventional solution-based conditions.

The exptl. investigation of intermol. charge transport in π-conjugated materials is challenging. Herein, we describe the investigation of charge transport through intermol. and intramol. paths in single-mol. and single-stacking thiophene junctions by the mech. controllable break junction (MCBJ) technique. We found that the ability for intermol. charge transport through different single-stacking junctions was approx. independent of the mol. structure, which contrasts with the strong length dependence of conductance in single-mol. junctions with the same building blocks, and the dominant charge-transport path of mols. with two anchors transited from an intramol. to an intermol. path when the degree of conjugation increased. An increase in conjugation further led to higher binding probability owing to the variation in binding energies, as supported by DFT calculations

A series of ten 2-naphthyl and 2-anthrylbithiophene derivatives with electron acceptor groups were synthesized using the Negishi or Suzuki cross-coupling reaction as a key step. We present a comparison of theor. and exptl. values of the LUMO and gap energies of these derivatives and the effect of the various electron-withdrawing groups on their optical and electrochem. properties. DFT-calculated frontier orbital energy differences have shown a trend following the exptl. determined values. The participation of the electron-withdrawing group in π-conjugation decreases the LUMO level and narrows the energy gap in the order of perfluoroalkyl, acyl, perfluoroacyl, nitro ≈ dicyanovinyl in both series. TD-DFT calculations allowed better understanding of electronic transitions. X-ray structure anal. of naphthalene hexanoyl and perfluorooctanoyl derivatives revealed their herringbone or sandwich herringbone mol. packing, resp., having a planar naphthalene-bithiophene moiety with opposite (s-trans vs. s-cis) conformation of bithiophene.

Yang, Zongfan; Hao, Wenjing; Su, Xi; Zhang, Ting; Chen, Weihua; Zhang, Guang; Chen, Long published the artcile< Metallosalphen-Based 2D Covalent Organic Frameworks with an Unprecedented tju Topology via K-Shaped Two-in-One Monomers>, Reference of 3480-11-3, the main research area is preparation transition metal salphen covalent organic framework topol condensation; transition metal salphen COF photocatalytic bromination methyl phenyl ether.

Increasing research interest was raised in two-dimensional covalent organic frameworks (2-dimensional COFs) probably due to their intriguing structural features and versatile functions. However, due to the relatively limited configuration of precursors, the documented 2-dimensional COFs to date were limited to only nine topologies which greatly restricts their development. Herein, the authors newly designed and synthesized three K-shaped two-in-one building units (Ni-Salphen, Cu-Salphen, and Zn-Salphen), which not only feature a special configuration distinguished from the reported monomers but also integrate metallosalphen functional moieties. Self-polycondensation of these K-shaped monomers facilely afforded three new metallosalphen-based COFs (Ni-Salphen-COF, Cu-Salphen-COF, and Zn-Salphen-COF) with an unprecedented tju topol. (tju = Tianjin University) that does not exist in the database of ToposPro. Regarding to the densely and uniformly distributed metallosalphens in the skeletons, the photocatalytic bromination performance of the three COFs were further investigated. Among them, Ni-Salphen-COF exhibited the highest performance on both conversion efficiency (>99%) and selectivity (>90%).

Albano, Gianluigi; Colli, Tony; Biver, Tarita; Aronica, Laura Antonella; Pucci, Andrea published the artcile< Photophysical properties of new p-phenylene- and benzodithiophene-based fluorophores for luminescent solar concentrators (LSCs)>, COA of Formula: C8H5BrS2, the main research area is photophys property phenylene benzodithiophene based fluorophore luminescent solar concentrator.

In this study, we report on the synthesis of new organic fluorophores containing either the p-phenylene or the benzodithiophene cyclic nucleus connected to thiophene units via triple bonds and carbonyl group, and on their application for the fabrication of luminescent solar concentrators (LSCs). Their optical properties were evaluated. Independent of the core, dyes containing the CO-thiophene residues seem to be the most promising for LSCs applications. In fact, carbonyl groups slightly enhance the quantum yield but significantly increase the red-shift of the emission so that the superimposition between the absorbance spectrum and the emission one is diminished. In the case of the benzodithiophene center, light emission in the yellow-red portion of the spectrum is achieved. The latter dye is then selected for tests in a poly(Me methacrylate) (PMMA) matrix. It showed good compatibility and homogenous distribution, no auto-absorption phenomena, and optical efficiencies of about 8% at 1 weight %, i.e. comparable with those PMMA/Lumogen Red films in the same range of concentration

An array of semiconducting oligoselenophenes (n and p types), up to hexamer units, e.g., I were synthesized by the double Stille coupling methods using tetrakis(triphenylphosphine)palladium(0) as a catalyst. A series of semiconducting oligomers (n and p types) containing mixed hetero-units (hexamers of thiophene and selenophene), e.g., II were also synthesized using the Stille coupling reaction. Their thermal properties were systematically studied and compared with those of π-conjugated thiophene based oligomers using DSC and TGA. The field-effect mobility of synthesized n and p type oligomers was analyzed.
