  Improved and new syntheses of potential molecular electronics devices

  摘要：

  New syntheses of ethyl and nitro substituted oligo(phenylene ethynylene)s (OPEs) have been developed. To further explore whether the presence of nitro functionality in OPEs leads to switching and memory capabilities, new nitro substituted OPEs have been designed and synthesized. An isatogen-based system, a structure that is isomeric to the nitro OPE, has been synthesized. Additionally, pyridine-based and chromium-based compounds have been synthesized. We surmise that redox reactions of these candidates may impart switching capabilities and electrochemical studies are shown. U-shaped OPEs were synthesized to inhibit leakage of metals deposited during formation of top contacts on self-assembled monolayers (SAMs). The OPEs contain either thiol-based moieties or isonitrile groups to enable formation of SAMs on metal substrates. (C) 2003 Elsevier Science Ltd. All rights reserved.

  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。
