The past decade has seen many improvements in the synthesis and characterization of nanometer-sized metal particles which have interesting potential applications in various fields, such as catalysis, optics and electronics. These nano-objects are almost exclusively stabilized by thiolate molecules, which limit their grown and allow their recovery as powders that can be re-dissolved. When particles are capped by bifunctional molecules, they can react with incoming molecules (over-grafting reactions) in order to modify their crown and then their characteristics. It is of special interest to follow the evolution of nanoparticles properties induced by crown modifications. Whereas most of the papers describing such an approach deal with gold nanoparticles, the present work reports on platinum nanoparticles.
