An aromatic coupling motif for two-dimensional supramolecular architectures.
We show, using scanning tunneling microscopy, how a coupling motif based on self-complementary helical aromatic units is able to drive the formation of a chiral porous supramolecular network and chains based on lateral aromatic interactions in two dimensions.
