报道了两种新型含主链邻苯二甲酰亚胺的噻吩共聚物的合成和表征。薄膜光学和广角X射线衍射测量表明，这两种聚合物都具有扩展的电子共轭和紧密的分子间pi堆积。由这些聚合物制备的薄膜晶体管的环境载流子迁移率高达0.28 cm(2)/(V S)，通断比大于10(5)。
The synthesis and characterization of two new thiophene copolymers with backbone phthalimide units is reported. Thin-film optical and wide-angle X-ray diffraction measurements indicate extended electronic conjugation and close intermolecular pi-stacking for both polymers. Ambient carrier mobility of thin-film transistors prepared from these polymers is as high as 0.28 cm(2)/(V s) with an on/off ratio greater than 10(5).
