Topological patterns of the supramolecular self-organization of small molecules held together by their common hydrogen bonds. (a) Heterochiral dimers in a linear array (pattern 1); (b) OC and OH dimers in a lateral array (sub-patterns 2a and 2b); (c) dimers in a lateral, but antiparallel array (sub-patterns 3a and 3b); (d) homochiral helices held together by heterochiral dimers in a linear array (sub-patterns 4a and 4b); (e) enantiomeric helices, held together by tetramers in a lateral array (sub-patterns 5a and 5b). |
