9528429 Martin Monodisperse conductive polymer nanowires and tubules can be prepared by synthesizing the desired polymer within the pores of nanoporous filtration membranes. The primary objective of this proposal is to use the template method to investigate the effects of molecular and supermolecular structure on electronic conduction in conductive polymers. Specifically, measurements of the temperature and pressure dependence of conductivity, the field dependence of conductivity, and the temperature and pressure dependence of the magnetoresistence, photoconductivity, and Hall effect will be used to explore how structure affects hopping distance, localization length, and density of states at the Fermi level in template-synthesized electronically conductive polymers. %%% The largest impediment to a thorough understanding of electronic conduction in conductive polymers is the inability to prepare samples whose properties can be reproducibly and predictably controlled. Template-synthesis allows for this type of structural control and thus provides a unique opportunity to explore the fundamentals of electronic conduction in these materials. ***

9528429 Martin 单分散导电聚合物纳米线和管可以通过在纳米多孔过滤膜的孔内合成所需的聚合物来制备。 该提案的主要目的是利用模板方法研究分子和超分子结构对导电聚合物电子传导的影响。 具体来说，测量电导率的温度和压力依赖性、电导率的场依赖性以及磁阻、光电导和霍尔效应的温度和压力依赖性，将用于探索结构如何影响模板合成的电子导电聚合物中费米能级的跳跃距离、局域长度和态密度。 %%% 彻底了解导电聚合物中电子传导的最大障碍是无法制备可重复且可预测控制其特性的样品。 模板合成允许这种类型的结构控制，从而提供了探索这些材料中电子传导基础的独特机会。 ***
