单分子芯片是量子信息处理的基础器件。在此背景下，实现了具有嵌入极性聚（甲基丙烯酸甲酯）基质中的方酸衍生的轮烷的非极性SM的芯片，并且在室温下观察到由电场诱导的SM荧光滞后。在这里，我们提出了一个模型，同时考虑电子转移和空间电荷弛豫过程来解释荧光滞后效应，基于模型的模拟与实验结果相当吻合。(C)2014 AIP出版有限责任公司。
Single molecule (SM) chips could serve as the fundamental devices in quantum information processing. In this context, a chip with the non-polar SMs of squaraine-derived rotaxanes embedded in a polar poly(methyl methacrylate) matrix was realized and the SM fluorescence hysteresis induced by the electric field was observed at room temperature. Here, we presented a model considering both of the electron transfer and space charge relaxation processes to explain the fluorescence hysteresis effect, and the model-based simulations agreed reasonably well with the experimental results.
