<jats:title>Abstract</jats:title><jats:p>Ions appear as active components in diverse materials. Here, the bonding energy between mechanically interlocked molecules (MIMs) or their acyclic/cyclic molecular derivatives and i) Cl<jats:sup>−</jats:sup> and Br<jats:sup>−</jats:sup> ions and/or ii) Na<jats:sup>+</jats:sup> and K<jats:sup>+</jats:sup> ions, have been investigated. The chemical environment provided by MIMs is less preferably to recognize ionic species compared to unconstrained interactions that are furnished by acyclic molecules. However, MIMs can be more adequate structures for ionic recognition than cyclic compounds if a chemical arrangement of the bond sites that relevantly support more favorable interactions with ions compared to Pauli repulsive ambient is provided. The hydrogen replacement by electron donor (−NH<jats:sub>2</jats:sub>) or acceptor (−NO<jats:sub>2</jats:sub>) groups in MIMs favors the anion/cation recognition due to decreased Pauli repulsion energy and/or more attractive non‐covalent bonds. This study clarifies the chemical environment provided by MIMs to interact with ions and highlights these molecules as relevant structures to realize ionic sensing.</jats:p>
