Solid-state enantiopure organic nanocubes formed by self organization of a C3-symmetrical tribenzotriquinacene.
Cubic aggregation: The racemic C(3)-symmetrical tribenzotriquinacene 1 was synthesized and found to crystallize in cubic aggregates consisting of eight homochiral molecules. The major driving force for this unique supramolecular aggregation may be attributed to the 24 equivalent sub-van der Waals interactions between the bromine atoms located at the convex surface of the triquinacene cores, rather than to polar interactions between the nitrobenzene units within and between the nanocubes.
