Nanometer-sized particles of metals and semiconductors have been investigated intensively because of their size-dependent properties and the possibility of arranging them in micro assemblies (and nano assemblies). Nanosized metal particles possess unique chemical and physical properties that can be exploited in a wide variety of technological applications, including catalysis, nonlinear optics ultra-purification and microelectronics. One of the design strategies that has shown tremendous potential as a viable route by which to produce metal nanoparticles with improved size control and colloidal stability is to employ polymeric matrixes as the form of growth media. In this presentation, we will disclose a new approach to synthesis and stabilization of nanosized novel metal nano particles. Our synthetic design is based on the need to generate catalytically active nonpassivated nanoparticles under mild reaction conditions and high yields. In this novel approach, cyclic siloxycynoureates are utilized to accomplish duel function of macromolecular stabilizing template as well as reducing agents. The details of synthetic design, nanoparticle properties and their catalytic activity will also be discussed.
