ABSTRACT Proposal Number: CTS-9312760 P.I.: Rubner Institution: M.I.T. The primary objective of this research is to develop the chemistry and nanoscale processing techniques needed to control the molecular and supermolecular organizations of electroactive conjugated polymers. This work is driven by the notion that the unique optical and electrical properties of these fascinating materials can be successfully tailored at the molecular level if suitable techniques are developed to manipulate and control the manner in which they organize in the solid state. To accomplish this goal, two new layer-by-layer molecular self-assembly processes recently discovered in our laboratory will be investigated; the self-assembly of conjugated polyions and the self-assembly of the p-type doped conducting polymers. The ability to readily fabricate multilayer thin films of conjugated polymers via molecular self-assembly processes is expected to open up completely new vistas with regard to the thin film processing of conducting polymers and related electoactive materials. In addition, self-assembled films can be used to fabricated and examine new heterostructure based thin film devices and sensors and to tailor the electrical and optical properties of various surfaces at the molecular level. The multilayer and heterostructure thin films fabricated with these new techniques will be characterized and evaluated in the form of various technologically relevant thin film devices such as thin film capacitors and Schottky light emitting diodes.

摘要 提案编号：CTS-9312760 P.I.： 机构：麻省理工学院 本研究的主要目的是开发控制电活性共轭聚合物的分子和超分子组织所需的化学和纳米级加工技术。 这项工作是由这样一种概念驱动的，即如果开发出合适的技术来操纵和控制它们在固态中组织的方式，这些迷人材料的独特光学和电学性质可以在分子水平上成功地定制。 为了实现这一目标，两个新的层层分子自组装过程最近发现在我们的实验室将进行研究：共轭聚离子的自组装和p型掺杂的导电聚合物的自组装。 通过分子自组装过程轻松制造共轭聚合物多层薄膜的能力预计将为导电聚合物和相关电活性材料的薄膜加工开辟全新的前景。 此外，自组装膜可用于制造和检测基于异质结构的新型薄膜器件和传感器，并在分子水平上定制各种表面的电学和光学性质。 多层和异质结构薄膜制造这些新技术的特点和评价的形式，各种技术相关的薄膜器件，如薄膜电容器和肖特基发光二极管。
