作为有机场效应晶体管的关键组成部分,有机半导体材料直接决定了器件的性能和稳定性。相比于p-型有机半导体材料,n-型和双极性有机半导体材料在迁移率和稳定性等方面则显著滞后。因此,n-型和双极性小分子有机半导体材料的设计与合成已成为高性能OFETs的学术研究的焦点。这篇综述重点突出了近十年报道的具有较好性能的n-型和双极性小分子有机半导体材料,并且对其结构和性能的关系进行了归纳,旨在对设计合成高性能、空气稳定的n-型和双极性有机小分子半导体材料提供一些指导帮助。
As a key part of organic field effect transistors, organic semiconductor materials directly determine the performance and stability of the devices. Compared to p-type organic semiconductor materials, n-type and bipolar organic semiconductor materials are significantly lagging in terms of mobility and stability. Therefore, the design and synthesis of n-type and bipolar small-molecule organic semiconductor materials have become the focus of academic research on high-performance OFETs. This review highlights the good performance of n-type and bipolar small-molecule organic semiconductor materials reported in recent ten years and their relationship with the structure and performance of organic semiconductors. The purpose of this review is to evaluate the design and synthesis of high performance, Stable n-type and bipolar organic small molecule semiconductor materials provide some guidance and assistance.
