  Orthogonally Functionalized Oligomers for Controlled Self-Assembly

  摘要：

  The synthesis of molecules terminated with complementary thiol-protecting groups is described. The target compounds contain functionalities on one end known to form self-assembled monolayers on metal surfaces while at the other end an intact thioacetate is present whereby self-assembly may again occur after an in situ deprotection. Self-assembly data is reported for selected compounds to assess their efficacy in surface adhesion.

  Presented here are several convergent synthetic routes to conjugated oligo(phenylene ethynylene)s. Some of these oligomers are free of functional groups, while others possess donor groups, acceptor groups, porphyrin interiors, and other heterocyclic interiors for various potential transmission and digital device applications. The syntheses of oligo(phenylene ethynylene)s with a variety of end groups

  本文介绍了几种共轭低聚（亚苯基乙炔基）合成路线。这些低聚物中的一些不含官能团，而其他则具有供体基团，受体基团，卟啉内部以及用于各种潜在传输和数字设备应用的其他杂环内部。提出了具有各种端基的低聚（亚苯基亚乙炔基）的合成方法，该低端基用于连接许多金属探针和表面。一些功能化分子系统表现出线性，线状，电流对电压（I（V））响应，而另一些则表现出负差分电阻（NDR）和分子随机存取记忆效应的非线性I（V）曲线。最后，描述了可以在金属电极上形成自组装单分子层的功能化低聚物的合成，从而降低了肖特基势垒。肖特基势垒研究的信息可以为分子电子学中的分子鳄鱼夹优化提供有用的见解。

  macrocycles are model compounds to investigate a hypothetical intramolecular interaction of the nitro group with the opposite macrocyclic subunits and ii) the nitro group(s) result in limited thermal stability of the compounds due to the intramolecular rearrangement to macrocycles comprising isatogen subunits. These highly functionalized macrocycles have been assembled by acetylene scaffolding strategies

  报道了大环 1 和 2 作为模型化合物的设计和合成，用于研究分子连接中的负微分电导现象。大环 1 和 2 包含由三个乙炔基连接的苯环组成的分子棒亚基。虽然两个末端苯环沿杆轴的旋转自由度受到大环框架的限制，但中心苯环是旋转的。棒子结构末端用乙酰基保护的硫醇基团官能化，以使其固定在金触点之间。中心苯环分别用一个和两个硝基官能化，分别代表 1 和 2。硝基特别重要，因为 i) 两个大环都是模型化合物，用于研究硝基与相反大环亚基的假设分子内相互作用，以及 ii) 硝基导致化合物的热稳定性有限，因为分子内重排为包含 isatogen 亚基的大环化合物。这些高度官能化的大环化合物是通过乙炔支架策略结合官能团转化化学组装而成的。 (© Wiley-VCH Verlag GmbH & Co.

  The present invention comprises three-terminal molecules devices that provide an electronic switching or modulation function in response to an electric field that is optimally directed normally to the length of the molecule or molecules which form the conductive path between tow electrodes. This invention also provides synthetic routes that can be implemented to realize these devices using top-down and bottom-up fabrication approaches that are compatible with ultra-high density integration onto substrates.

  We report a new redox/cycloaddition cascade on readily available 1-alkynyl-2-nitrobenzenes that produces complex azacyclic compounds stereoselectively. The core structures of the resulting products are constructed through a formal [2 + 2 + 1] cycloaddition among a-carbonyl carbenoids, nitroso species, and external alkenes.

  A Cu-promoted cyclization of 2-nitrophenyl iodoacetylenes provides a direct route to a range of 2-iodoisatogens. These compounds represent useful intermediates for the late-stage elaboration of the C-I bond to furnish isatins and a range of alternative heterocyclic products.
