Sulfate anion-templated assembly of a [2]catenane.
نویسندگان
چکیده
The sulfate anion's templating role in catenane formation is demonstrated for the first time; a novel bis-pyridinium nicotinamide [2]catenane is prepared in a remarkable high yield and is shown to exhibit selectivity for sulfate, the templating anion.

Anion templated double cyclization assembly of a chloride selective [2]catenane.
The interweaving of two identical acyclic positively charged anion recognizing units around a chloride anion template leads to the formation of an orthogonal supramolecular ensemble which upon subsequent double ring cyclization gives a chloride selective [2]catenane in very high yield.
متن کاملAnion-templated calix[4]arene-based pseudorotaxanes and catenanes.
We present the rational design and anion-binding properties of the first anion-templated pseudorotaxanes and catenanes in which the "wheel" component is provided by a calix[4]arene macrobicyclic unit. The designs and syntheses of two new calix[4]arene macrobicycles, 2 and 3, are presented, and the abilities of these new species both to bind anions and to undergo anion-dependent pseudorotaxane f...
متن کاملAnion templated assembly of mechanically interlocked structures.
This tutorial review describes the evolution of the field of chemical templation, in particular, emphasising the impact its application has made to the synthesis of mechanically interlocked structures. Recent advances in the use of negatively charged template species for the synthesis of interlocked structures are detailed, with the main focus of this review describing the development of a gene...
متن کاملSulfate-templated self-assembly of new M4L6 tetrahedral metal organic cages.
Six equivalents of N,N'-bis(4-aminobenzyl)urea, 12 equivalents of 2-formylpyridine and four equivalents of FeSO(4) or NiSO(4) undergo subcomponent self-assembly in aqueous solution to form tetrahedral cages around a single, encapsulated sulfate anion.
متن کاملA Catenane Assembled through a Single Charge-Assisted Halogen Bond**
Interlocked molecules have captured chemists imagination owing to their nontrivial topology and the promise of their potential nanotechnological uses as molecular machines and in chemical sensor applications. The synthesis of such sophisticated architectures is a challenge, and as a consequence this has necessitated the implementation of imaginative cation, anion, and neutral templation methodo...
