Abstract

original image

Fest verschnürt: Ein vierfaches Rotaxan wurde aus einem Porphyrin-Molekül mit vier Alkylammoniumketten und einer Phthalocyanin-Einheit mit vier Kronenetherresten erhalten. Das Rotaxan bildete einen zweikernigen Cu2+-Komplex, in dem die Cu2+-Porphyrin- und Cu2+-Phthalocyanin-Einheiten so effektiv geschichtet waren, dass die ungepaarten Elektronenspins, deren Zustände reversibel geschaltet wurden, in Wechselwirkung traten (siehe Bild).
