  摘要：

  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。

  This Article reports a systematic study on the formation of self-assembled monolayers (SAMs) of conjugated molecules for molecular electronic (ME) devices. We monitored the deprotection reaction of acetyl protected dithiols of oligophenylene ethynylenes (OPEs) in solution using two different bases and studied the quality of the resulting SAMs on gold. We found that the optimal conditions to reproducibly form dense, high-quality monolayers are 9-15% triethylamine (Et3N) in THF. The deprotection base tetrabutylammonium hydroxide (Bu4NOH) leads to less dense SAMs and the incorporation of Bu4N into the monolayer. Furthermore, our results show the importance of the equilibrium concentrations of (di)thiolate in solution on the quality of the SAM. To demonstrate the relevance of these results for molecular electronics applications, large-area molecular junctions were fabricated using no base, Et3N, and Bu4NOH. The magnitude of the current-densities in these devices is highly dependent on the base. A value of beta = 0.15 angstrom(-1) for the exponential decay of the current-density of OPEs of varying length formed using Et3N was obtained.
