这里介绍了共轭低聚（亚苯基亚乙炔基）的几种聚合合成路线。这些低聚物中的一些不含官能团，而另一些则具有供体基团、受体基团、卟啉内部和其他杂环内部，用于各种潜在的传输和数字设备应用。介绍了具有多种端基的低聚（亚苯基亚乙炔基）的合成，用于连接到多种金属探针和表面。一些功能化分子系统表现出线性、线状、电流与电压 (I(V)) 响应，而另一些则表现出负微分电阻 (NDR) 和分子随机存取记忆效应的非线性 I(V) 曲线。最后，描述了功能化低聚物的合成，其可以在金属电极上形成自组装单层，从而减少肖特基势垒。来自肖特基势垒研究的信息可以为分子电子学的分子鳄鱼夹优化提供有用的见解。
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 for attachment to numerous metal probes and surfaces are presented. Some of the functionalized molecular systems showed linear, wirelike, current versus voltage (I(V)) responses, while others exhibited nonlinear I(V) curves for negative differential resistance (NDR) and molecular random access memory effects. Finally, the go syntheses of functionalized oligomers are described that can form self-assembled monolayers on metallic electrodes that reduce the Schottky barriers. Information from the Schottky barrier studies can provide useful insight into molecular alligator clip optimizations for molecular electronics.
