在这里，我们提出了一种新的溶液加工的n型掺杂剂，N-DMBI的发展。我们的实验结果表明，一个著名的n沟道半导体，[6，6]-苯基C-61丁酸甲酯（PCBM），可以有效地掺杂N-DMBI的溶液处理，薄膜的电导率显着增加的n型掺杂。我们首次利用这种n型掺杂来改善n沟道有机薄膜晶体管的空气稳定性，其中掺杂可以补偿电子陷阱。我们使用N-DMBI成功演示了n型掺杂，为开发空气稳定的n沟道半导体开辟了新的机会。它也是潜在的有用的应用在溶液处理的有机发光二极管和有机光致发光器件。
We present here the development of a new solution-processable n-type dopant, N-DMBI. Our experimental results demonstrated that a well-known n-channel semiconductor, [6,6]-phenyl C-61 butyric acid methyl ester (PCBM), can be effectively doped with N-DMBI by solution processing; the film conductivity is significantly increased by n-type doping. We utilized this n-type doping for the first time to improve the air-stability of n-channel organic thin-film transistors, in which the doping can compensate for the electron traps. Our successful demonstration of n-type doping using N-DMBI opens up new opportunities for the development of air-stable n-channel semiconductors. It is also potentially useful for application on solution-processed organic light-emitting diodes and organic photovoltaics.
