Abstract

The 2-iodoimidazolium group is exploited in the anion-templated assembly of pseudorotaxanes with isophthalamide containing macrocycles. Crystallographic and solution-phase studies illustrate that the iodo-imidazolium motif is a potent halogen bond donor, forming the most stable interpenetrated assemblies in solution with the chloride anion template.
