摘要
Machines at a molecular level are in perpetual Brownian motion even at an ambient temperature. One of the representative issues of researches on molecular machines is a development of technology, which can control Brownian motion. This review presents our efforts to achieve the first rationally designed molecular brake systems of threading/dethreading motions, a shuttling motion, and a rocking motion that work reversibly and quantitatively in response to external stimuli without producing any chemical wastes. These molecular brake systems were constructed from a dumbbell shaped secondary ammonium axle and a ring component having photo and thermally reactive moiety.
