Coulomb’s law tells us that opposing charges attract and like charges repel. Recently our group showed that supramolecular assemblies can overcome Coulombic repulsion with bisulfate (HSO4−) in dichloromethane (Figure 1). Taking this idea further, we examined the effect of solvophobic interactions, ion-pairing, and anion solvation on the formation of different assemblies of the HSO4− and H2PO4− anions with cyanostar. In order to test how these different driving forces affect anion driven co-assembly in the presence of a hydrogen bonding anion, solvent was used as the variable parameter. Quantitative understanding of the assembly of cyanostar and self-associating anions will be presented.
