We investigated the lateral morphological organization of a liquid crystall
ine material at binary heterogeneous surfaces, composed of the distribution
of nanoscale domains of one molecular compound, within the continuum of a
second molecular phase. These surfaces were shown to generate well-organize
d lateral microstructures, whose length scale, as compared to the underlyin
g nanodomains size, is by 3 orders much larger, demonstrating the absence o
f any discrete contribution from the nanoscale domains. On the basis of the
se results, a modulation (cooperative-like effect) of the surface forces ar
ising from the surface structures was proposed, which drives the overall we
tting properties, structure formation, and related morphological transition
s at these nanoheterogeneous surfaces.
