Key Points

To establish a supramolecular structural framework for 1,3-dialkylimidazolium ionic liquids across solid, liquid, and solution phases, challenging the assumption that they behave as simple homogeneous solvents.
Synthesized structural and physical-chemical evidence governing 1,3-dialkylimidazolium salts across solid, liquid, and gas states.
Evaluated structural disruptions and domain reorganization occurring upon the introduction of external molecules and macromolecules into the ionic liquid matrix.
Pure 1,3-dialkylimidazolium ionic liquids organize into extended hydrogen-bonded polymeric supramolecular networks of the type {[(DAI)x(X)x-n)]n+ [(DAI)x-n(X)x)]n-}n.
This hydrogen-bonded structural motif persists robustly from the solid crystal lattice into the liquid phase and even into the gas phase.
Introduction of external solutes cleaves the hydrogen bond network, generating segregated polar and non-polar nanoscale regions capable of forming inclusion-type compounds.
