聚合物半导体材料因其可溶液加工的特点在构筑大面积、价廉、柔性有机器件方面引起了人们的广泛兴趣。但是,通常情况下,器件中聚合物半导体薄膜都是通过旋涂方式制备,该薄膜中分子的有序性差而且存在大量的晶界和缺陷,这不利于聚合物半导体材料本征性能的合理评价和高性能聚合物光电器件的制备。因此,如何制备高取向聚合物薄膜一直是该领域研究的一个热点。本论文对我们课题组在聚合物半导体材料的取向化(如,通过基底诱导)和结晶化(如,缓慢自组装)及通过聚合物微纳晶揭示材料本征性能和构筑高性能器件等方面的工作做了一个简单的总结。
Polymer semiconductors have attracted widespread interest in structuring large-area, inexpensive, and flexible organic devices for their solution-processing properties. However, in general, all the polymer semiconductor films in the device are prepared by the spin-coating method. The films have poor molecular ordering and a large number of grain boundaries and defects, which is unfavorable for the reasonable evaluation of the intrinsic performance of the polymer semiconductor materials And the preparation of high performance polymer optoelectronic devices. Therefore, how to prepare highly oriented polymer films has always been a hot spot in this field. In this paper, we focus our research group on the orientation of polymer semiconductors (eg, through substrate induction) and crystallization (eg, slow self-assembly) and revealing the intrinsic properties of materials and building high-performance devices through polymer micro- The work done a simple summary.
