摘　　要：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。Semiconducting polymer materials have attracted particular attention in organic electronics because of their ideal solution-processed ability for low cost,large area,flexible organic devices.But polymer semiconductors in devices are always fabricated by spin-coating in film state.In the films polymer molecules are highly disorder and there are full of grain boundaries and defects etc.,so that the valuation of polymer semiconductor intrinsic properties and the fabrication of high performance devices are full of challenges.In this mini-account,we briefly summarize our recent studies on the alignment of polymer semiconductors by substrate inducing epitaxy and self-assembly etc.,the valuation of polymer intrinsic properties by their nanocrystals as well as the applications of the aligned polymer films and nanocrystals for high performance optoelectronic devices.
