Molecular semiconductors synergize a variety of uniquely advantageous properties such as excellent absorption and emission properties, soft and deformable mechanical properties, and mixed ionic and electrical conduction. Over the past two decades, this outstanding set of features has put molecular semiconductors in the spotlight for a variety of optoelectronics and sensing applications. When it comes to mass-market adaptation, however, a challenge in these soft and van der Waals-bonded materials remains their electrical as well as environmental stability and degradation. This Prospective will summarize some of our current understanding of why organic semiconductors degrade with a strong emphasis put on the quintessential role played by water in this process. Furthermore, it will be revisited by which mechanisms water-related stability shortcomings might be addressed in the future and how these lessons can be translated to relevant hybrid systems such as perovskites and carbon nanotubes. Throughout this discussion, some parallels and key differences between organic and hybrid materials will be highlighted, and it will be elaborated on how this affects the associated device stability.

克服分子和混合半导体中与水有关的稳定性挑战的观点

分子半导体协同各种独特的优势特性，如优异的吸收和发射特性、柔软和可变形的机械特性以及混合离子和电传导。在过去的二十年里，这组杰出的特性使分子半导体成为各种光电和传感应用的焦点。然而，当谈到大众市场适应时，这些软和范德瓦尔斯粘合材料的挑战仍然是它们的电气以及环境稳定性和降解性。本展望将总结我们目前对有机半导体降解原因的一些理解，并着重强调水在此过程中所起的典型作用。此外，将重新审视未来可能解决与水相关的稳定性缺陷的机制，以及如何将这些经验转化为相关的混合系统，如钙钛矿和碳纳米管。在整个讨论中，将强调有机材料和混合材料之间的一些相似之处和主要区别，并将详细说明这如何影响相关的设备稳定性。
