A simple self-propelled motor on a 4-[[(dodecyloxy)benz-4-yl]azo]benzoic acid (DBA) molecular layer was investigated from the viewpoint of motor control depending on the molecular structure. The nature of the self-motion of a camphor disk on the DBA molecular layer changed depending on the surface pressure (π)-area (A) isotherm of DBA, which in turn changed by the photoisomerization between UV and green lights. The characteristic motion of the camphor disk is discussed in relation to the π-A isotherm of DBA, which changes depending on the photoisomerization as the driving force of motion.
从取决于分子结构的电机控制角度出发，对基于4-[[(十二烷氧基)苯-4-基]偶氮]苯甲酸（DBA）分子层的简单自推进电机进行了研究。樟脑盘在DBA分子层上的自运动性质随DBA的表面压力（π）-面积（A）等温线而变化，而该等温线又因紫外光和绿光之间的光异构化而改变。结合DBA的π-A等温线讨论了樟脑盘的特征运动，该等温线随作为运动驱动力的光异构化而变化。
