Abstract

During the past ten years, the performance of polymeric field-effect transistors has been largely improved, not only in mobility but also in durability. Among the factors contributed to such improvements, side-chain engineering plays an important role. Various techniques, such as branch point adjustment, hydrogen-bonding introduction and the incorporation of other functional groups in the side-chain were developed, which greatly altered the crystallinity, alignment and morphology of the conjugated polymers hence their charge transport behavior. In this review, the side-chain engineering strategies that have been employed in polymeric field-effect transistors are summarized and discussed in detail, which we hope could provide an insight into further development in this area.

摘要

在过去的十年中，聚合物场效应晶体管的性能不仅在迁移率方面而且在耐用性方面都得到了很大的提高。在促成此类改进的因素中，侧链工程扮演着重要角色。开发了各种技术，例如支化点调节，氢键引入以及在侧链中引入其他官能团，这些技术极大地改变了共轭聚合物的结晶度，排列和形态，因此改变了它们的电荷传输行为。在这篇综述中，对聚合物场效应晶体管中已采用的侧链工程策略进行了总结和详细讨论，我们希望可以对这一领域的进一步发展提供一个见识。
