Semiconductors are widely used in electron devices. With the development of wearable soft-electron devices, conventional inorganic semiconductors are unable to meet the demand because of their high rigidity and high cost. Thus, scientists construct organic semiconductors with high charge mobility, low cost, eco-friendly, stretchable, etc. Due to the excellent performance of stretchable organic semiconductors, they can be widely used as wearable soft-electron devices, such as stretchable organic field-effect transistors (OFETs), organic solar cells (OSCs), etc. Contains flexible display devices and flexible power sources, which are of great interest for applications of future electron devices. However, there are still some challenges that need to be solved. Commonly, enhancing the stretchability may cause the degradation of charge mobility, because of the destruction of the conjugated system. Currently, scientists find that hydrogen bonding can enhance the stretchability of organic semiconductors with high charge mobility. Thus in this review, based on the structure and design strategies of hydrogen bonding, various hydrogen bonding induced stretchable organic semiconductors are introduced. In addition, the applications of the hydrogen bonding induced stretchable organic semiconductors are reviewed. Finally, the stretchable organic semiconductors design concept and potential evolution trends are discussed. The final goal is to outline a theoretical scaffold for the design of high-performance wearable soft-electron devices, which can also further advance the development of stretchable organic semiconductors for applications.
半导体广泛应用于电子器件中。随着可穿戴软电子器件的发展，传统无机半导体因其高刚性和高成本而无法满足需求。因此，科学家们构建了具有高电荷迁移率、低成本、环保、可拉伸等特性的有机半导体。由于可拉伸有机半导体的优异性能，它们可广泛用作可穿戴软电子器件，如可拉伸有机场效应晶体管（OFET）、有机太阳能电池（OSC）等。包含柔性显示器件和柔性电源，这对于未来电子器件的应用具有极大的吸引力。然而，仍然存在一些需要解决的挑战。通常，提高可拉伸性可能会导致电荷迁移率下降，这是由于共轭体系的破坏。目前，科学家们发现氢键可以提高具有高电荷迁移率的有机半导体的可拉伸性。因此，在本综述中，基于氢键的结构和设计策略，介绍了各种氢键诱导的可拉伸有机半导体。此外，还综述了氢键诱导的可拉伸有机半导体的应用。最后，讨论了可拉伸有机半导体的设计概念和潜在的发展趋势。最终目标是勾勒出高性能可穿戴软电子器件设计的理论框架，这也可以进一步推动可拉伸有机半导体在应用方面的发展。
