背景技术半导体广泛用于电子器件中。随着可穿戴软电子设备的发展,传统的无机半导体由于其高刚性和高成本而无法满足需求。因此,科学家构建具有高电荷迁移率的有机半导体,低成本,环保,可拉伸,等。由于可拉伸有机半导体的优异性能,它们可以广泛用作可穿戴的软电子设备,如可拉伸有机场效应晶体管(OFET),有机太阳能电池(OSC),等。包含柔性显示设备和柔性电源,这对未来电子设备的应用非常感兴趣。然而,还有一些挑战需要解决。通常,增强可拉伸性可能会导致电荷迁移率的下降,因为共轭系统的破坏。目前,科学家发现,氢键可以增强具有高电荷迁移率的有机半导体的拉伸性。因此,在这次审查中,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,综述了氢键诱导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。最终目标是为高性能可穿戴软电子器件的设计勾勒出一个理论支架,这也可以进一步促进可拉伸有机半导体应用的发展。
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.
