The first anion‐templated synthesis of a lanthanide‐containing interlocked molecule is demonstrated by utilizing a nitrite anion to template initial pseudorotaxane formation. Subsequent stoppering of the interpenetrated assembly allows for the preparation of a lanthanide‐functionalized [2]rotaxane in high yield. Following removal of the nitrite anion template, the europium [2]rotaxane host is demonstrated...
Pseudorotaxane wurden aus einem Halogenbrücken(XB)‐Akzeptor (rot im Schema) und verschiedenen XB‐Akzeptoren als lineare Komponenten hergestellt, wobei eine Halogenbrücke die Synthese steuerte. Die Stärke der XB‐kontrollierten Anordnung wurde in der Synthese eines [2]‐Catenans ausgenutzt, die durch Ringschlussmetathese erfolgte.
