Organic semiconductors have received broad attention and research interest due to their unique integration of semiconducting properties with structural tunability, intrinsic flexibiltiy and low cost. In order to meet the requirements of organic electronic devices and their integrated circuits, p-type, n-type and ambipolar organic semiconductors are all necessary. However, due to the limitation in both material synthesis and device fabrication, the development of n-type and ambipolar materials is quite behind that of p-type materials. Recent development in synthetic methods of organic semiconductors greatly enriches the range of n-type and ambipolar materials. Moreover, the newly developed materials with multiple functions also put forward multi-functional device applications, including some emerging research areas. In this review, we give a timely summary on these impressive advances in n-type and ambipolar organic semiconductors with a special focus on their synthesis methods and advanced materials with enhanced properties of charge carrier mobility, integration of high mobility and strong emission and thermoelectric properties. Finally, multi-functional device applications are further demonstrated as an example of these developed n-type and ambipolar materials.
有机半导体由于其独特的半导体性能与结构可调性、本征柔韧性和低成本的结合，受到了广泛的关注和研究兴趣。为了满足有机电子器件及其集成电路的要求，p 型、n 型和双极性有机半导体都是必需的。然而，由于材料合成和器件制造的限制，n 型和双极性材料的发展远远落后于 p 型材料。有机半导体合成方法的最新发展极大地丰富了 n 型和双极性材料的范围。此外，具有多种功能的新型材料也提出了多功能器件应用，包括一些新兴的研究领域。在这篇综述中，我们特别关注其合成方法以及具有增强电荷载流子迁移率、集成高迁移率和强发光性能以及热电性能的先进材料，及时总结了 n 型和双极性有机半导体令人瞩目的进展。最后，以这些开发的 n 型和双极性材料为例，进一步展示了多功能器件应用。
