abstract = {Langmuir monolayers of chiral amphiphiles are
well-controlled model systems for the investigation of
phenomena related to stereochemistry. Here, we have
investigated mixed monolayers of one pair of enantiomers (L
and D) of the amino-acidbased amphiphile
N-stearoyl-threonine. The monolayer characteristics were
studied by pressure−area isotherm measurements and grazing
incidence X-ray diffraction (GIXD) over a wide range of
mixing ratios defined by the D-enantiomer mole fraction
$x_D$. While the isotherms provide insights into
thermodynamical aspects, such as transition pressure,
compression/decompression hysteresis, and preferential homo-
and heterochiral interactions, GIXD reveals the molecular
structural arrangements on the Ångström scale. Dominant
heterochiral interactions in the racemic mixture lead to
compound formation and the appearance of a nonchiral
rectangular lattice, although the pure enantiomers form a
chiral oblique lattice. Miscibility was found to be limited
to mixtures with 0.27 ≲ $x_D$ ≲ 0.73, as well as to both
outer edges ($x_D$ ≲ 0.08 and $x_D$ ≳ 0.92). Beyond this
range, coexistence of oblique and rectangular lattices
occurs, as is clearly seen in the GIXD patterns. Based on
the results, a complete phase diagram with two eutectic
points at $x_D$ ≈ 0.25 and $x_D$ ≈ 0.75 is proposed.
Moreover, N-stearoyl-threonine was found to have a strong
tendency to form a hydrogen-bonding network between the
headgroups, which promotes superlattice formation.},
