A scalable synthesis of swallow-tailed quaterrylene diimides (STQDIs) and a method for the solution processing of sparingly soluble quaterrylene diimide (QDI) thin films are described. The pressure-assisted thermal cleavage of swallow tails yields crystalline QDI layers with electron mobility up to 0.088 cm2 V-1 s-1. The developed method opens up a new route toward the solution processing of higher rylene diimides with poor solubility.
Pronounced supramolecular order in discotic donor-acceptor mixtures

Mixing a hexa-peri-hexabenzocoronene (HBC) derivative and a perylene- or terrylenediimide results in the formation of complex helical arrangements in the columnar superstructures. Weak donor-acceptor interactions between the electron-rich HBC and the electron-poor rylene dye lead to strictly alternating and long-range-ordered stacks. The mixtures display homeotropic orientation on surfaces (picture shows an image from an optical microscope). (Chemical Equation Presented).

The present invention relates to liquid-crystalline rylenetetracarboxylic acid derivatives, to processes for their preparation and to their use as n-type organic semiconductors for producing organic field-effect transistors and solar cells.
Pentarylene- and hexarylenebis(dicarboximide)s: Near-infrared-absorbing polyaromatic dyes

(Figure Presented) In the red: The synthesis and optical properties of homologous ladder-type near-infrared-absorbing chromophores, namely, two pentarylenebis(dicarboximide)s (green traces; see picture) as well as a hexarylenebis(dicarboximide) (yellow trace) have been studied. A strong bathochromic shift of the absorption maximum is noted with an increasing degree of annulation as is evident from the other traces.
