By using nanojars as anion binding agents, selectivity for either carbonate or sulfate can be achieved upon rigidification of the nanojar outer-shell with tethers of varying lengths between pairs of pyrazole ligands.

<div>We report the synthesis of a novel macrocyclic host molecule that forms in a single step from commercially available starting materials. The core of the macrocycle backbone possesses two quinone rings and, thus, is redox-active. Host-guest binding involving the clip-shaped cavity indicates selective binding of pyridine <i>N</i>-oxides based of the electron density of and steric bulk of the anionic oxygen.</div>

The use of tethers between ligands allows for the preparation of novel multimetallic complexes, not obtainable without tethers, and leads to unexpected properties, such as selective binding of the carbonate vs. sulfate anion by nanojars.
