Racemic and Optically Pure Heptahelicene‐2‐carboxylic Acid: Its Synthesis and Self‐Assembly into Nanowire‐Like Aggregates (Eur. J. Org. Chem. 5/2011)

The cover picture shows heptahelicene-2-carboxylic acid, whose synthesis and self-assembly are central to the article. The background features Prague's riverbank, which is intermixed with the nanowire-like aggregates of heptahelicene-2-carboxylic acid. The alignment of the swans makes the link between self-assembly and the Prague view. Details are discussed in the article by I. G. Stara, I. Starý, A. Kuhnle et al. on p. 853 ff.
