Tiling patterns : Rubrene (C 42 H 28 ) molecules self‐assemble on a gold surface to create a two‐dimensional tiling with a combination of slightly distorted supramolecular pentagons, hexagons, and heptagons. Both periodic and nonperiodic tessellations are observed, as well as circular singularities in extended honeycomb domains, formed by the replacement of a ring of twelve hexagons by six pentagon‐heptagon pairs.
