摘要

Artificial molecular switches have been the robust tools for diverse fields of modern science and technology,including molecular machines,smart materials,and bioimaging [1].The development of new concepts to enable the creation of efficient molecular switches has been a longstanding activity in these fields.Up to date,various kinds of molecular switches have been developed,most of which work between two or more stable states,and the rest of them requires at least an additional energy or chemical stimuli.Such a working fashion normally suggests an inconvenience and the possibility of dual fatigue accumulation [2].Based on nonequilibrium action controls,however,molecules with self-recoverability offer a very straightforward approach to improve operation convenience and fatigue resistance,which is quite difficult to be realized by traditional molecular switches.
