ABSTRACT
Hydrogen bond (HB) mediated base pair motifs are versatile scaffolds of diverse supramolecular constructs. Here, we report that two new four- and six-membered supermacrocyclic assemblies with intriguing geometries could self-assemble from two new adenine derivatives, APN (1) and APC (2). The conversion of a conventional HB acceptor, N8 of 1, to a non-conventional HB donor, C8-H of 2, had a pronounced impact on the overall intricate HB network and self-assembly patterns, epitomizing the subtleties in design and exploitation of such base-pair motifs as promising tectons for building supramolecular architectures.
