2-(2-Methoxyphenyl)-1,3-dimethyl-1H-benzoimidazol-3-ium iodide (o-MeO-DMBI-I) was synthesized and employed as a strong n-type dopant for fullerene C(60), a well-known n-channel semiconductor. The coevaporated thin films showed a maximum conductivity of 5.5 S/cm at a doping concentration of 8.0 wt% (14 mol%), which is the highest value reported to date for molecular n-type conductors. o-MeO-DMBI-I can be stored and handled in air for extended periods without degradation and is thus promising for various organic electronic devices.
2-(2-甲氧基苯基)-1,3-二甲基-1H-苯并咪唑-3-鎓碘化物（o-MeO-DMBI-I）被合成出来，并被用作富勒烯 C(60)的强 n 型掺杂剂，富勒烯 C(60)是一种众所周知的 n 型半导体。共蒸发的薄膜在掺杂浓度为 8.0 wt%（14 mol%）时表现出最大的电导率为 5.5 S/cm，这是迄今为止报道的最高值，用于分子 n 型导体。o-MeO-DMBI-I 可以在空气中长期储存和处理而不会降解，因此有望用于各种有机电子器件。
