摘　　要：有机电子学的最终目标是实现简单地构筑高性能逻辑电路以满足各种应用需求.双极性有机半导体,特别是双极性共轭聚合物,在制备可溶液印刷、低成本和大面积的有机电路方面具有独特的优势.然而,本征双极性聚合物的窄带隙导致其电流开关比低(通常为10~2-10~3),阻碍了输出信号的高精度和抗干扰性,而这是潜在逻辑电路应用的关键要求.本文中,基于可控掺杂的工艺,本征平衡双极性聚合物实现了准单极传输特性,其p沟道和n沟道薄膜晶体管的电流开关比均显著提高至10~5-10~7.此外,可控掺杂的有机逻辑电路如非门、或非门、与非门通过直写印刷技术构建,其具有优异的综合性能,高达150的增益值和68%的信号噪声容限以及快速响应.本工作通过掺杂策略显著地提高了双极性材料的开关比,可为双极性材料在印刷集成电路中的实际应用提供理论基础.Organic electronics aims to simplify the construction of high-performance basic logic circuits for various applications.Ambipolar organic semiconductors,particularly ambipolar conjugated polymers,offer distinct advantages of easy solution-printing-based fabrication and low-cost development of large-area organic circuits.However,the narrow bandgaps of intrinsic ambipolar polymers result in the low current on/off ratio(generally 10~2-10~3),impeding the generation of output signals with high accuracy and immunity,which are critical requirements for potential logic circuit applications.The quasi-unipolar transport properties for pristine well-balanced ambipolar polymers were obtained using a controllable-doping process,which resulted in a significant increase in current on/off ratios(10~5-10~7)for both p-channel and n-channel thin-film transistors.Furthermore,large-area organic logic circuits such as NOT,NOR,and NAND gates were constructed using a direct writing technique based on the same ambipolar conjugated polymer films with superior pand n-conducting channels by the controllable-doping process,demonstrating excellent overall performance with a high gain value of~150,signal noise margins of 68%and fast response to input voltages.This study provides valuable guidelines for improving the on/off ratio of ambipolar materials by implementing the doping strategy,further promoting the possibility of practical applications in solution-printed integrated organic circuits.
