Coordination-induced formation of submicrometer-scale, monodisperse, spherical colloids of organic-inorganic hybrid materials at room temperature.

In this communication, we demonstrate a novel coordination-based strategy to the fabrication of submicrometer-scale, monodisperse, spherical colloids of organic-inorganic hybrid materials, carried out by mixing H2PtCl6 and p-phenylenediamine (PPD) aqueous solutions at room temperature. The particle size and polydispersity can be controlled by the molar ratio and concentration of reactants, and the optimum experimental parameters for the production of monodisperse colloids are also given.
