中文摘要： 共轭聚合物作为一种典型的有机光电应用材料已经与微纳图案化加工过程密不可分，而在纳米图案化加工过程提供的纳米受限环境下的共轭聚合物凝聚态结构对材料的性能和应用产生重要的影响，因此关于纳米受限条件下的共轭聚合物凝聚态结构调控的研究有着重要的理论和实际意义。本项目利用纳米压印技术对共轭聚合物进行纳米图案化，研究在纳米图案化过程中不同受限条件对聚合物凝聚态结构的影响作用，将纳米结构的构筑和凝聚态结构的调控有机统一起来，并且将受限条件下的凝聚态调控应用到有序异质结太阳能电池的构建中，研究出不同受限条件下共轭聚合物纳米图案的构筑、凝聚态结构的调控和材料性能之间的内在联系。这不仅将对纳米加工受限条件下的共轭聚合物凝聚态结构调控方法会有一个系统全面的认识，而且也对共轭聚合物的性能优化和加工应用具有重要的指导意义。

英文摘要： The conjugated polymer has been regarded as one of typical photo-electricity materials and has an inextricable connection with micro/nano-pattern process, however, the control over the aggregate structure of conjugated polymer under the nano-confinement, owing to the nano-pattern processing, is a key element in determining polymer property and application. Therefore, the conjugated polymer aggregate structure under nano-confinement becomes one of the most significant research topics in the fields of polymer theory and application. The aim of this project is to focus on the nano-confinement effect on the aggregate structure of conjugated polymer during the nano-pattern processing, where the polymer nanostructure array will be fabricated by the aid of the nanoimprinting lithography method. Furthermore, the control of conjugated polymer aggregate structure under confinement is employed to effectively fabricate ordered polymer/fullerene bulk heterojunction solar cells, to investigate the effect of molecular structure on solar cell performance. In the end, it will be obtained the relationship among the fabrication process of nano-pattern, the government of aggregate structure and material property of conjugated polymer under varied confinement effect. Then, it will also provide new insight and guidance for controlling the aggregate structure of conjugated polymer and may lay a significant foundation for application and improvement of conjugated polymer nanostructure.
