It is well known that the size and shape of silver nanoparticles determines their catalytic, electronic, and optical properties. Therefore it is important to develop an effective method for the preparation of the nano materials with well-controlled shapes and sizes. In this study, size- and shape-controlled synthesis of silver nanoparticles were performed through the reduction of intermediates of Ag-S inorganic/organic hybrid polymers having supramolecular structures (Ag-SR polymers). The Ag-SR polymers were simply prepared by mixing alkanethiols with the solution of silver salts. We prepared various sizes of monodisperse silver nanoparticles by heating, chemical reduction, and E-beam irradiation. The sizes and shapes of the nanoparticles were characterized by transmission electron microscopy (TEM). The detail results will be given in the meeting.
