Stepwise Dissipative Control of Multimodal Motion in a Silver(I) Catenate

Abstract

Stepwise dissipative control of two distinct motions, i.e., shuttling and sliding, is demonstrated in a single multicomponent device. When [2]rotaxane 1, which acts as a biped, and deck 2 were treated with AgBF4 / PhCH2Br + NEt3 as chemical fuel, the transient catenate [Ag(1)]+•[Ag3(2)]3+ was instantly generated showing multimodal motion and autonomous return to 1 and 2. In the dissipative process, catenate [Ag(1)]+•[Ag3(2)]3+ cleanly transformed into the follow‐up transient device (1)•[Ag3(2)]3+ exhibiting only sliding motion. Two interference‐free dissipative cycles proved the resilience and robustness of the process.
