Alternating naphthyridine–pyrimidine strands self‐organize into a helical conformation containing a strongly polar cavity. The binding of metal and ammonium cations promotes supramolecular self‐assembly in a sort of effector‐induced growth process to form polymolecular stacks (see schematic representation) and fibers observable by electron microscopy. Such entities offer features of molecular ion channels.
