Light‐Harvesting in Multichromophoric Rotaxanes

Chemistry – A European Journal, 2011
AbstractTwo rotaxanes with benzyl ether axles and tetralactam wheels were synthesized through an anion template effect. They carry naphthalene chromophores attached to the stopper groups and a pyrene chromophore attached to the wheel. The difference between the two rotaxanes is represented by the connecting unit of the naphthyl chromophore to the ...

Azofarbstoff‐Rotaxane

Angewandte Chemie, 1997
Hydrophobe Wechselwirkungen wurden für die Selbstorganisation von Azofarbstoffen und Makrocyclen zu den stabilen Rotaxanen 1 genutzt. Eingeschlossen von α‐Cyclodextrin, β‐Cyclodextrin oder einem Cyclophan, wurden die hantelförmigen Azofarbstoffe durch Azokupplung im wäßrigen Medium synthetisiert.magnified ...

Glycylglycin‐Rotaxane — Wasserstoffbrückenvermittelte Selbstorganisation synthetischer Peptid‐Rotaxane

Angewandte Chemie, 1997
Nicht eingefädelt wird der Glycylglycin‐Faden (unten links) in Benzylamid‐Makrocyclen, diese werden vielmehr um das Peptid herum aufgebaut; dabei wirken die Amidgruppen des Dipeptids als Templat, und es entstehen Peptid‐[2]rotaxane (unten rechts). Die vier Wasserstoffbrücken zwischen den Ausgangsverbindungen, durch die eine Cyclisierung ermöglicht wird,

Rotaxanes and Polyrotaxanes

2019
In this chapter, the preparation of cucurbituril-based pseudorotaxanes, rotaxanes and polyrotaxanes is illustrated with selected examples. This includes the notions of self-sorting, which enables the setup of homo- and hetero(pseudo)rotaxanes. The implications of thermodynamic and kinetic control are briefly showcased as well.
