abstract = {The speculated presence of monomolecular lamellae of
antagonisticsalts in oil−water mixtures has left several
open questions besides theirhypothetical existence,
including their microscopic structure and
stabilizationmechanism. Here, we simulate the spontaneous
formation of supramolecularaggregates of the antagonistic
salt sodium tetraphenylborate (NaBPh4) in waterand
3-methylpyridine (3-MP) at the atomistic level. We show
that, indeed, thelamellae are formed by a monomolecular
layer of the anion, enveloped by 3-MPand hydrated sodium
counterions. To understand which thermodynamic forcesdrive
the aggregation, we compare the full-atomistic model with a
simplified onefor the salt and show that the strong
hydrophobic effect granted by the largeexcluded volume of
the anion, together with electrostatic repulsion, suffice to
explain the stability of the monomolecular lamellae.},
