科幻小说和电影中常将宏观的物体缩小到微纳米尺寸,而后将其送入人体内执行各种任务.然而,无论是将物体缩小(“从上而下”),还是利用原子或分子堆砌成具有功能的机器(“自下而上”),都曾经只是人们的科学幻想.20世纪90年代以来,利用超分子化学的方法构建的分子机器一步步从想象走到了现实,受到科学界的瞩目,Jean-Pierre Sauvage,Sir J.Fraser Stoddart和Bernard L.Feringa三位科学家也因设计和合成出分子马达 In science fiction and movies, macroscopic objects are often reduced to micro-nano dimensions, which are then fed into the human body to perform a variety of tasks.However, both the reduction of objects (“top down”) and the use of atoms or molecules Piled up as functional machines (“bottom-up”) were once just people’s science fantasies. Since the 1990s, molecular machines constructed by using supramolecular chemistry have come step by step from imagination to reality The scientific community’s attention, Jean-Pierre Sauvage, Sir J.FraserStoddart and Bernard L.Feringa three scientists also because of the design and synthesis of molecular motor
