                                    A molecular motor that has been previously shown to rotate when fueled by electrons through a scanning tunneling microscope tip has been functionalized with a terarylene photochrome fragment on its rotating subunit. Photoisomerization has been performed under UV irradiation. Variable-temperature 1H NMR and UV–vis studies demonstrate the rotational motion and its braking action after photoisomerization
                                    以前已经显示出一种分子电动机,当通过扫描隧道显微镜的尖端由电子提供燃料时,该电动机会旋转,并已在其旋转亚基上使用了亚芳基光致变色片段进行了功能化。在UV辐射下已经进行了光异构化。可变温度1 H NMR和UV-vis研究证明了光异构化后的旋转运动及其制动作用。制动作用可以通过加热来逆转。一旦获得了刚性且平面闭合的形式,在较低的温度下旋转将有效地减慢,从而使这种新型转子成为具有对电子和光的独立响应的潜在电动机。
