近年来，分子人工马达的合成和研究取得了巨大的发展。一个挑战是设计由“干净”刺激驱动的机器。如果能源的使用（几乎）没有副产品，没有副产品，没有稀释或任何其他破坏性影响，则能源类型被认为是“清洁”的刺激。我们在此提出了一种由光和电驱动的推动电机，两者都被认为是“清洁”的刺激。马达的开关单元是偶氮苯和噻蒽。前者是由光引发的，而后者改变其结构的结果是通过循环伏安法实现的氧化还原过程。用量子化学方法和紫外/维斯光谱确定了分子马达的四个态。开关周期可以执行几次，而信号没有显著变化。
The synthesis and investigation of molecular artificial motors have been subject to massive developments in recent years. One challenge is to design machines driven by "clean" stimuli. Types of energies are considered as "clean" stimuli if their use leads to (almost) no side-products, no byproducts, no dilution, or any other disruptive effects. We present herein a pushing motor that is driven by light and electricity, both being considered as "clean" stimuli. The switching units of the motor are an azobenzene and a thianthrene. The former is triggered by light, whereas the latter changes its structure as a result of a redox process achieved by cyclic voltammetry. The four states of the molecular motor were identified by quantum chemical methods and UV/Vis spectroscopy. The switching cycles can be performed several times without significant changes in the signals.
