Artificial transistors represent an ideal means for meeting the requirements in interfacing with biological systems. It is pivotal to develop new proton-conductive materials for the transduction between biochemical events and electronic signals. Herein, the first demonstration of a porous organic polymer membrane (POPM) as a proton-conductive material for protonic field-effect transistors is presented. The POPM is readily prepared through a thiourea-formation condensation reaction. Under hydrated conditions and at room temperature, the POPM delivers a proton mobility of 5.7 × 10 cm V s ; the charge carrier densities are successfully modulated from 4.3 × 10 to 14.1 × 10 cm by the gate voltage. This study provides a type of promising modular proton-conductive materials for bioelectronics application.
人工晶体管是满足与生物系统接口要求的理想手段。开发用于生化事件与电信号转换的新型质子传导材料至关重要。在此，首次展示了一种多孔有机聚合物膜（POPM）作为质子场效应晶体管的质子传导材料。通过硫脲形成缩合反应可轻松制备POPM。在水合条件和室温下，POPM的质子迁移率为5.7×10 cm V s；通过栅极电压成功将载流子密度从4.3×10调制到14.1×10 cm。该研究为生物电子应用提供了一种有前景的模块化质子传导材料。
