In this "Perspectives" article, we highlight the role of cation-anion interactions in the formation and structure of newly documented POM monolayers on metal nanoparticles, abd establish a unifying principle for better understanding the self-assemly of diverse supramolecular structure from highly charge molecular-ion building blocks.

Cryo-TEM images and UV-vis spectroscopy show that electrostatic interactions between polyoxometalates (POMs) and structurally incorporated counter-cations control the self-assemly of POM-monolayers on gold nanoparticles. In the graphic, caesium cations are used to "manufacture" Preyssler-ion ligand shells on 14-nm gold nanoparticles in water.

Cryogenic transmission electron microscopy of polyoxometalate-protected gold nanoparticles reveals that the Preyssler ion, [NaP5W30O110]14-, lies "face down" with its C5 axis perpendicular to the gold surface, while the Finke-Droege ion, [P4W30Zn4(H2O)2O112]16-, is "tilted", with its long axis close to 60 from the normal to the surface.
