Nitrite-Templated Synthesis of Lanthanide-Containing [2]Rotaxanes for Anion Sensing**

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 d...

Polyoxotungstate-encapsulated Gd(6) and Yb(10) complexes.

A new synthetic method for polynuclear lanthanoid complexes that are embedded in molecular polyoxotungstates has afforded the highest nuclearity polyoxometalate-encapsulated Gd complex and the first decanuclear Yb complex of any sort to be structurally characterized.

Single ion magnets based on lanthanoid polyoxomolybdate complexes.

Polyoxometalate (POM) chemistry has recently offered excellent examples of single ion magnets (SIMs) and molecular spin qubits. Compared with conventional coordination compounds, POMs provide rigid and highly symmetric coordination sites. However, all POM-based SIMs reported to date exhibit a very limited range of possibilities for chemical processability. We present herein two new families of ...

Lanthanide cation-templated synthesis of rotaxanes.

The first lanthanide cation-templated synthesis of an interlocked structure is demonstrated through an interpenetrated assembly between a pyridine N-oxide threading component coordinating to a lanthanide cation complexed within a macrocycle. Stoppering of the pseudo-rotaxane assembly allows for preparation of the [2]rotaxane.
