Graphical Abstract

Swapping partners: The presence of N-oxide functions in double-helical dimers formed from oligo(pyridinecarboxamide)s promotes heterodimerization (see picture). This process mimicks the essence of base pairing and information storage in DNA through heterologous A/T and G/C Watson–Crick base pairing.
