Research output: Contribution to journalArticlepeer-review


The controllable mechanical movement of either the polyether macrocycle or the tetracationic cyclophane in a doubly bistable water-soluble [2]catenane can be accomplished by using orthogonal external stimulia-redox and amine/acid, respectivelya-in aqueous media .
