面向能源的高效、稳定共轭高分子光电转换材料的制备是竞争非常激烈的国际前沿研究领域。但目前开发的聚合物材料效率普遍较低，制约其效率提高的主要原因之一是低的载流子迁移。这是有机电子材料迈向实用化的瓶颈，也是光电领域带有共性、亟需解决的问题。. 本项目拟系统地研究外电场对共轭高分子有序结构的调控及载流子迁移特的影响。旨在揭示外电场作用下不同极性、不同尺度链长共轭高分子有序结构形成、调控及载流子迁移特性提高的规律与新机制；实现外场操纵下共轭高分子有序结构和迁移率大小的动态调控。从高分子本征性质入手，提高光电器件水平。这是光电转换材料设计的新思路、新方法，国内外尚未见报道。研究具有很强的创新性及挑战性，其中蕴藏巨大的宝库等待人们去探索和发掘。因此，本研究具有重要的科学意义和研究价值。

Facing with energy, the preparation of highly effective and stable photoelectric conversion materials based on the conjugated polymer is the international foreland research fields with fierce competition. However the efficiency of the current developed polymer photovoltaic cells is generally low. The low carrier mobility is one of the main barriers to improve the efficiency. This is a bottleneck to put conjugated polymer photovoltaic conversion materials in use, and also a common issue to be solved in the field of photoelectricity.. This project will systematicly study the effect of the external electric field on the control of the ordered structure of conjugated polymer and the characteristics of the carrier mobility. The study aims at revealing the formation and control of the ordered conjugated polymer with different polarity and scales, the law and new mechanism of improving the characteristics of the carrier mobility; achieving dynamic control of the ordered conjugated polymer and strength of the carrier mobility under the control of the external electric field. In order to improve the level of photoelectric devices, we will start with the intrinsic property of polymer. It is a new concept and method designing the photoelectric conversion materials, which has not been reported in China and abroad. The research is like a huge treasure to be excavated, which is greatly innovative and challenging. Therefore, the research has important scientific meanings and study values.
