TL;DR: In this paper, the authors describe the preparation of large, yet well-defined, nanoscale polycyclic aromatic hydrocarbons (PBAHs), which then self-assemble to highly ordered, supramolecular arrays with advantageous electronic properties.

TL;DR: A new route to ladder-type pentaphenylenes has been developed in which both good hole-accepting p-type and electron- acceptance n-type materials can be prepared from a common intermediate, suggesting that this unit could be used to greatly increase the injection of electrons into polymers containing it in a light-emitting diode (LED) or solar cell.

TL;DR: The first synthesis of perylene-3,4:9,10-tetracarboxylic acid diimides combining the properties of water solubility and fluorescence quantum yields (FQYs) close to unity is presented, which makes them attractive as high-performance fluorescence probes in aqueous media.

TL;DR: Compared to the normal alkyl-subsituted hexabenzocoronenes (HBCs), 14a-c exhibit more highly ordered columnar mesophases, including three-dimensionally ordered superstructures (helical columnar Mesophase) that could arise from additional intracolumnar pi-pi interactions between, and space-filling requirements introduced by, the rigid-rod side groups.

TL;DR: The substitution of a hexa-peri-hexabenzocoronene by bulky, space-demanding, 2-decyltetradecyl side chains proved to be an effective procedure to influence the thermal and self-aggregation behavior of this compound, leading to aligned columnar superstructures as revealed by 2D-WAXS experiments.
