Low-power, flexible, and properly encapsulated integrated circuits are the basic requirements of the solution-processed printed and wearable electronic prototypes for various emerging applications including display circuits, sensors, and radio-frequency identification tags. The organic field-effect transistor is one of the important types of devices used in such prototypes and its industrial applicability is essential for the printed electronics technology. The performance deterioration upon encapsulated through the thick layer of air-stable dielectric material such as amorphous fluoropolymer [CYTOP] - must be compensated by device engineering. In this work, we used furan and thiophene flanked diketopyrrolopyrrole donor-acceptor conjugated polymers namely PDPPF-DTT and PDPPT-DTT, and its comparative study was performed using Cytop as a dielectric material. The work advances interface engineering towards the single-gate and dual-gate organic transistors. Dual-gate transistors performance modulation using Cytop dielectric opens new research avenues towards stability enhancement of such transistors for real-world applications.

低功耗、灵活和适当封装的集成电路是解决方案处理的印刷和可穿戴电子原型的基本要求，用于各种新兴应用，包括显示电路、传感器和射频识别标签。有机场效应晶体管是此类原型中使用的重要器件类型之一，其工业适用性对于印刷电子技术至关重要。通过厚层空气稳定介电材料（如无定形含氟聚合物 [CYTOP]）封装后的性能下降必须通过器件工程进行补偿。在这项工作中，我们使用呋喃和噻吩侧翼的二酮吡咯并吡咯供体-受体共轭聚合物，即 PDPPF-DTT 和 PDPPT-DTT，并使用 Cytop 作为介电材料进行了比较研究。这项工作推进了单栅和双栅有机晶体管的界面工程。使用 Cytop 电介质的双栅极晶体管性能调制为此类晶体管在实际应用中的稳定性增强开辟了新的研究途径。
