Abstract
We report the structural transition of a phosphonium ionic liquid-based microemulsion from the bulk to nanoconfined between atomically flat micas. Upon the nanoconfinement, we observed a firmly surface-adsorbed ionic liquid film that stabilizes the nanoconfined microemulsion. Further confinement (<11 nm) induces rearrangements in the microemulsion culminating into two well-ordered layers with slow dynamics.
