Ionic interactions of microspheres. Reversible coating of Prussian blue nanoparticles on the submicrospheres of platinum(II) complexes

The submicrospherical morphology is conveniently formed by a reaction of platinum(II) species in water with new pyridyl ligand in acetone, and followed by evaporation of acetone. The amphiphilic properties of ionic platinum(II) complex containing a long aliphatic chain allow to form a monodisperse submicrosphere morphology without any template or additive. A reversible coating of Prussian blue nanoparticles on the submicrospheres has been carried out. Furthermore, the submicrospheres form a unique monolayer on a micro cotton thread or a glass fiber. The ionic and amphiphilic properties of the surface appear to be primarily associated with the easy formation of coating and arrays of monolayer.
