摘要
为了研究n型有机混合离子电子导体电子-离子双响应特性及分子量对载流子迁移率的影响,采用具有平面刚性的梯形分子链结构的高分子量聚苯并二咪唑苯并菲绕啉二酮制备高性能有机电化学晶体管,并对晶体管紫外可见吸收光谱和晶体管器件电气性能进行表征。结果表明,利用高分子量聚苯并二咪唑苯并菲绕啉二酮制备的n型有机电化学晶体管表现出极高的响应速度(0.034 s)、高载流子迁移率(4.72×10^(-3) cm^(2)/(V·s)),以及在水系电解液中优异的稳定性(稳定运行超过120次脉冲循环)。
In order to study the electron-ion dual response properties of n-type organic hybrid ion conductors and the effect of molecular weight on carrier mobility,high molecular weight poly(benzimidazobenzophenanthroline)with a planar rigid trapezoidal molecular chain structure was used to prepare high performance organic electrochemical transistors.The transistors were characterized by UV-visible absorption spectra and transistor device electrical properties.The results show that the n-type organic electrochemical transistors prepared by using high molecular weight poly(benzimidazobenzophenanthroline)exhibit extremely high responsiveness(0.034 s),high carrier mobility(4.72×10^(-3) cm^(2)/(V·s))and excellent stability(stable running over 120 pulse cycles)in aqueous electrolytes.
