Artificial molecular motors hold great promise for application in responsive functional materials as well as to control the properties of biohybrid systems. Herein a strategy is reported to modulate the rotation of light‐drivenmolecular motors. That is, the rotary speed of a molecular motor, functionalized with a biphenol moiety, could be decreased in situ by non‐covalent substrate binding, as was
人工分子电动机在响应性功能材料中的应用以及控制生物混合系统的性能方面具有广阔的前景。本文报道了一种调节光驱动分子马达旋转的策略。就是说,通过1 H NMR和UV / Vis光谱确定,通过双酚基团结合原位可以降低被双酚部分官能化的分子电动机的旋转速度。这些发现构成了发展多反应分子机制的重要一步。

arene-annulated polycyclic framework were constructed efficiently by a metal-free and atom economic acid-catalyzed method. The reactions could be performed by acid-catalyzed cationic cyclization and rearrangement under mild conditions. Moreover, the resulting polycyclic products showed highly twisted architectures with two perpendicular planes.
