有机混合离子电子导体（OMIECs）由于其在从传感、驱动和计算到能量收集/存储和信息传输的各种应用中的多功能性而获得了最近的兴趣和快速发展。它们的多功能特性来自于它们同时参与氧化还原反应以及调节整个材料本体中的离子和电子电荷密度的能力。最重要的是，通过大范围的状态密度和材料的物理体积来访问深度调制的电荷状态的能力，使基于OMIEC的器件能够显示令人兴奋的新特性，并在器件设计中开辟新的自由度。利用有机合成工具箱的无限可能性，这种观点强调了几种化学和结构设计方法，以修改OMIECs在设备应用中的重要特性，如电子和离子电导率，颜色，模量等。此外，OMIECs响应外部刺激和将信号转换为无数类型输出的能力加速了它们在智能系统中的发展。这个观点进一步说明了各种刺激，如电，化学和光学输入如何从根本上动态改变OMIEC的特性，以及如何在设备应用中利用这些变化。
Organic mixed ionic–electronic conductors (OMIECs) have gained recent interest and rapid development due to their versatility in diverse applications ranging from sensing, actuation and computation to energy harvesting/storage, and information transfer. Their multifunctional properties arise from their ability to simultaneously participate in redox reactions as well as modulation of ionic and electronic charge density throughout the bulk of the material. Most importantly, the ability to access charge states with deep modulation through a large extent of its density of states and physical volume of the material enables OMIEC‐based devices to display exciting new characteristics and opens up new degrees of freedom in device design. Leveraging the infinite possibilities of the organic synthetic toolbox, this perspective highlights several chemical and structural design approaches to modify OMIECs’ properties important in device applications such as electronic and ionic conductivity, color, modulus, etc. Additionally, the ability for OMIECs to respond to external stimuli and transduce signals to myriad types of outputs has accelerated their development in smart systems. This perspective further illustrates how various stimuli such as electrical, chemical, and optical inputs fundamentally change OMIECs’ properties dynamically and how these changes can be utilized in device applications.
