Topology Selection and Tautoleptic Aggregation: Formation of an Enantiomerically Pure Supramolecular Belt over a Helix

Abstract

In control: An enantiomerically pure monomer selects the formation of a supramolecular belt (see structure; blue N, red O, gray C, white H) over a helix. Induced tautomerization allows for a three-hydrogen-bond motif to be employed in cyclic homoleptic aggregation.
