Conjugated Polymers in Solution and in the Solid State

两个重要的方向提供了本研究的重点。一个目标是实现共轭聚合物在溶液和固体薄膜中的高量子效率光致发光。这种高效的发光聚合物薄膜旨在用于由导电聚合物制造的发光二极管(LED)。二是研究共轭聚合物-“巴基球”复合材料和由共轭聚合物-“巴基球”双层膜构成的p-n异质结中的高量子效率电荷分离。光诱导电荷转移类似于人工光合作用的关键步骤。对科学的更深入理解为从这种异质结制造的太阳能电池进行低成本、高效率的太阳能转换提供了可能性。导电聚合物现在被用作具有独特性能的材料：半导体和金属的重要电子和光学性能，以及聚合物的诱人的机械性能和加工优势。这项研究将为LED和人工光合作用用共轭聚合物中的pi电子的量子化学和物理提供基础科学研究。

Two important directions provide the focus of this research. One goal is to achieve high quantum efficiency photoluminescence from conjugated polymers in solution and in solid thin films. Such highly efficient luminescent polymer films are intended for use in light-emitting diodes (LEDs) fabricated from conducting polymers. The other is to study high quantum efficiency charge separation in conjugated polymer-"buckyball" composites and in p-n heterojunctions made from conjugated polymer-"buckyball" bilayers. The photoinduced charge transfer is analogous to the key step in artificial photosynthesis. A deeper understanding of the science offers the potential for low-cost efficient solar energy conversion from solar cells fabricated from such heterojunctions. Conducting polymers are now available as materials with unique properties: the important electronic and optical properties of semiconductors and metals in combination with the attractive mechanical properties and the processing advantages of polymers. The research will provide basic scientific research on the quantum chemistry and physics of the pi-electrons in conjugated polymers for LEDs and artificial photosynthesis.
