• Naphthalimide-containing conjugated polyelectrolytes with different chain configurations

  DOI：10.1039/c9ob00219g

  日期：——

  Several donor–acceptor type conjugated polyelectrolytes containing naphthalimide are developed. Different polymer chain configurations of the backbones of polymers lead to different photophysical properties. The para-substituted polymers show extended conformations with quite low quantum yields in high polarity solvents because of twisted intramolecular charge transfer features, while the meta-substituted

  Divalent inhibitors of the neuraminidase enzyme (NA) of the Influenza A virus were synthesized with vastly different spacers. The spacers varied from 14 to 56 atoms and were relatively rigid by way of the building blocks and their connection by CuAAC. As the ligand for these constructs, a Δ4-β-d-glucoronide was used, which can be prepared form N-acetyl glucosamine. This ligand showed good NA inhibitory

  甲型流感病毒的神经氨酸酶 (NA) 的二价抑制剂是用截然不同的间隔物合成的。间隔物从 14 到 56 个原子不等，并且通过构建块及其通过 CuAAC 的连接而相对刚性。作为这些构建体的配体，使用Δ 4 -β- d -葡糖苷酸，其可以由N-乙酰氨基葡糖制备。该配体显示出良好的 NA 抑制效力，但具有通过多价增强改进的空间。合成的化合物在 NA 活性测定中显示出适度的效力增强，但在 4 天的细胞病变效应测定中显示出相当大的效力增加。除了 NA 外，这些化合物还可以抑制血凝素的证明可能是增强的原因。
• p-Diethynylbenzene-based molecular wires, Fe–C C-p-C6H2X2–C C–Fe [Fe= Fe(η5-C5Me5)(dppe)]: Synthesis, substituent effects and unexpected formation of benzodifuran complex
  作者：Yumi Matsuura、Yuya Tanaka、Munetaka Akita

  日期：2009.5

  A series of p-diethynylbenzene- based molecular wires, Fe-C C-p-C6H2X2-C C-Fe (3) (Fe = FeCp* (dppe)), is prepared and their wire-like performance is estimated on the basis of the K-C and V-ab values. It has been revealed that electron-donating substituents (X) improve the performance. The benzodifuran complex 4 unexpectedly formed from the derivative with X = OH shows the performance comparable to 3. (C) 2009 Elsevier B.V. All rights reserved.

  A compound comprises a polymeric chain with a repeat unit repeated more than 5 times. The repeat unit comprises conjugated first and second cyclic groups and a plurality of side groups each bonded to one of the cyclic groups. A side group bonded to the first cyclic group is an electron donor and a side group bonded to the second cyclic group is an electron acceptor, such that the compound is switchable between first and second electrical conductive states by application of an electric field to the compound. At least one of the side groups is selected so that the compound is soluble in an organic solvent. The compound may be used in films, memory cells, or electronic devices. A layer of the compound may be formed on a surface by dissolving the compound in an organic solvent, applying the solution to the surface, and then removing the solvent.
