title: Star-shaped hexa-peri-hexabenzocoronene "heptamer": synthesis and self-assembly.
abstract: [structure: see text] A star-shaped hexa-peri-hexabenzocoronene "heptamer" was prepared, which showed a strong tendency to aggregate in solution and in the bulk states. Higher order was found in a high-temperature, columnar liquid crystalline phase due to the higher mobility of the molecules in comparison with the low-temperature solid. In addition, physical gel formation was observed due to the presence of covalent intercolumnar interactions.
