Abstract

original image

Ion-promoted, automorphogenic, and stoichiometric self-assembly of a hexameric, Ru-based macrocycle and a dendrimer produces a stable nanofiber. A structurally related larger 3rd generation dendrimer was reacted with [(112+)(PF6)12] to afford a neutral, sphere-like motif. These polyanionic counterions lead to ion-pair superstructures in which the randomness of single-charged counterions has been eliminated.
