随着生产纳米级机器的长期目标，我们在这里描述了由化学转化提供燃料的合成分子结构的单向旋转运动。旋转的基础是苯基转子相对于萘基定子围绕单键轴的运动。旋转的感觉由选择的化学试剂控制，这些化学试剂通过四个化学上不同的站为马达提供动力。在站内，转子通过限制转子相对于定子的布朗运动的程度的结构特征保持就位。
With the long-term goal of producing nanometer-scale machines, we describe here the unidirectional rotary motion of a synthetic molecular structure fueled by chemical conversions. The basis of the rotation is the movement,of a phenyl rotor relative to a naphthyl stator about a single bond axle. The sense of rotation is governed by the choice of chemical reagents that power the motor through four chemically distinct stations. Within the stations, the rotor is held in place by structural features that limit the extent of the rotor's Brownian motion relative to the stator.
