pound 1 could self-assemble into supramolecular organizations
from straight nanowires to well-organized microrods through a
two-level self-assembly process in a binary solvent of methanol/
dichloromethane. This process may well be used for other mole-
cules to fabricate new nanomaterials in the field of photoelectric
devices.

tering was observed, corresponding to the
p-stacking distance of
the large flat A cores along the 1D assembly columnar axis. This
is also supported by the single crystal X-ray data of the parent
compound heterotriangulene A, where the molecules pack into
1D column with a stacking distance of 3.5 Å [20,25]. The broaden-
ing peak at 3.4 Å suggests that either the stacking is less regular or
that the A cores are slightly tilted with respect to the columnar axis
[26]. Then, a large broad and diffuse scattering centered at around
4.5 Å was visible, which reflects the short-range correlations of the
alkyl chains. Finally, a very weak signal at 6.9 Å, which corresponds
to about twice the
p-stacking distance (ꢀ2d), may be due to some
kind of dimerization. In the slightly lower angle region, another
weak diffuse scattering peak corresponding to a distance of ca.
9.1 Å was attributed to some correlations of alkyl chains between
neighboring molecules. In the small-angle region, a sharp reflec-
tion peak at 2h = 3.06° was detected, from which a spacing of
a = 28.9 Å was estimated. This value corresponds to the spacing be-
tween the lateral 2D arrays. Its second-order reflection (28.9/n,
n = 2) appeared at approximately 14.8 Å. The sharpness and inten-
sity of the small-angle reflection at 2h = 3.06° indicate clearly the
long-range second level assembly between the 1D assembly col-
umns, which is formed by the first-level assembly of 1 due to the
intermolecular
p–p interactions of A cores. Overall, the two-level
self-assembly process can be illustrated in Fig. 3.

Due to the
p–p stacking interactions of A cores and the hydro-
phobic interactions of alkyl chains with solvent molecules, com-
