设计并合成了一系列六个苯基侧苯并二吡咯烷酮基共聚物：三个表现出主链的平面内曲率或扭转扭曲，而其他三个保持平面和线性。虽然前者通过X射线衍射可能看起来不那么结晶，但它们提供了更光滑的薄膜表面拓扑结构，并增加了顶栅底接触有机场效应晶体管中的电子迁移率。
A series of six phenyl-flanked benzodipyrrolidone-based copolymers are designed and synthesised: three exhibit backbone in-plane curvature or torsional twisting, while the other three remain planar and linear. While the former may appear less crystalline by X-ray diffraction, they afford a smoother thin-film surface topology and increased electron mobility in top-gate, bottom-contact organic field-effect transistors.
