Molecular electronic devices have gained extensive interest, owing to their low‐cost fabrication, easy characterization, low voltage operations, fast response to external stimuli, and innumerable applications that are not possible with the existing complementary metal‐oxide semiconductor (CMOS)‐based devices. Molecular ultrathin films of controllable thickness grown through the electroreduction method on conducting carbon electrodes can further enhance the interfacial stability of the molecular devices over thiolated self‐assembled monolayers, thus are more powerful for practical usages. A novel nanometric molecular electronic device with a stacking configuration of carbon/tetraphenylporphyrin/LiF/carbon demonstrates electric‐field‐ and polar‐solvent‐driven ion movements, producing high‐density charge storage ability and resonant charge‐transport mechanism at low bias <+1 V is highlighted here. The charge storage capability of the device enhances in CH₃CN vapor as much as 78 fold over the dry measurement.

分子电子设备中移动离子的运动

分子电子设备因其低成本的制造，易于表征，低电压操作，对外部刺激的快速响应以及无数的应用而受到了广泛的关注，而现有的基于互补金属氧化物半导体（CMOS）的设备无法实现这些应用。通过电还原方法在导电碳电极上生长的厚度可控的分子超薄膜可以进一步增强分子器件在硫醇化自组装单分子层上的界面稳定性，因此在实际应用中功能更强大。具有碳/四苯基卟啉/ LiF /碳的堆叠结构的新型纳米分子电子器件演示了电场和极性溶剂驱动的离子运动，此处着重介绍了在低偏压<+1 V时产生高密度电荷存储能力和谐振电荷传输机制的问题。设备的电荷存储能力在CH中得到增强₃ CN蒸气比干法测量高78倍。
