Comparison of the stacking periodicity along the columnar
axis and that along the molecular disc normal (h0 and h,
respectively) indicates that the molecules are stacked almost
perpendicular to the columnar axis (see Table S1 in the
Supporting Information).[16] Furthermore,the molecules
likely stack in an alternated fashion in order to fill the
available space between neighbors.This is also indicated by
molecular dynamics (MD) simulations in which a column
model was built from a periodic cylindrical cell with a 13.3-G
height (4 I 3.33 G,corresponding to four stacked molecules),
in keeping with the experimental X-ray data.These calculations
show a good space-filling of the available volume as
well as the enhancement of the microsegregation over the
entire simulation experiment time,contributing to the
cohesion of the columnar structure.Moreover,the model
showed that the cohesion of the columns is further reinforced
