有机混合导体在从生物电子学到能量存储/产生的应用中获得了极大的关注。它们在有机晶体管中的实现导致了增强的生物传感，神经形态功能和专用电路。虽然一小类导电聚合物在这些新应用中继续表现出色，但随着研究人员瞄准新的功能性、可加工性和改进的性能/稳定性，材料设计工作已经加速。有机电化学晶体管（OECTs）的材料需要有效的电子传输和容易的离子注入，以维持高容量。在这项工作中，我们证明了电子迁移率和体积电荷存储容量（µC*）的乘积是材料/系统的品质因数;我们使用这个框架来基准测试和比较10种先前报道的材料的稳态OECT性能。该产品可以独立验证和解耦，以指导材料设计和加工。因此，OECTs可以被用作理解和设计新的有机混合导体的工具。支持电子和离子传输的有机材料有望在生物电子学和能量存储中应用。在这里，Inal等人使用晶体管以电荷迁移率和体积电容的乘积来量化有机混合导体的材料性能。
Organic mixed conductors have garnered significant attention in applications from bioelectronics to energy storage/generation. Their implementation in organic transistors has led to enhanced biosensing, neuromorphic function, and specialized circuits. While a narrow class of conducting polymers continues to excel in these new applications, materials design efforts have accelerated as researchers target new functionality, processability, and improved performance/stability. Materials for organic electrochemical transistors (OECTs) require both efficient electronic transport and facile ion injection in order to sustain high capacity. In this work, we show that the product of the electronic mobility and volumetric charge storage capacity (µC*) is the materials/system figure of merit; we use this framework to benchmark and compare the steady-state OECT performance of ten previously reported materials. This product can be independently verified and decoupled to guide materials design and processing. OECTs can therefore be used as a tool for understanding and designing new organic mixed conductors. Organic materials that support both electronic and ionic transport hold promise for applications in bioelectronics and energy storage. Here, Inal et al. use transistors to quantify the materials performance of organic mixed conductors in terms of the product of charge mobility and volumetric capacitance.
