Abstract

original image

Die kontrollierte mechanische Bewegung von entweder dem Polyether-Makrocyclus oder dem tetrakationischen Cyclophan in einem doppelt-bistabilen wasserlöslichen [2]Catenan lässt sich durch Anwendung orthogonaler externer Stimuli (Redoxreaktionen bzw. Reaktion mit Amin/Säure) in wässrigem Medium erzielen (siehe Bild).
