Sulfate anion-templated assembly of a [2]catenane

abstract

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.
