Donor-acceptor (D-A) structures were obtained by alternating arrays of hexa-peri-hexabenzocoronene (HBC) and benzo[c][1,2,5] thiadiazole (BTZ). Optoelectronic investigations revealed a charge transfer due to strong push-pull interactions. 2D wide-angle X-ray scattering (WAXS) data indicated an arrangement in liquid-crystalline columnar assemblies, in which the pi-stacking distances and molecular orientation depend on the number of HBC units in the molecules.
