Abstract

We summarize our investigations on the formation of 2 nm to 4 nm metal and semiconductor nanoclusters with polyelectrolyte dendrimers as hosts. Poly(amidoamine) (PAMAM) dendrimers can be used as templates for inorganic colloids, both in aqueous solution and in a polymeric matrix. - SANS, SAXS and TEM are used to characterize the resulting hybrid structures. Different inorganic colloids like noble metal and cadmium sulfide colloids are studied.1- With increasing dendrimer generation, we observe a transition from low molecular colloid stabilizing to an effective electrostatic nanotemplating . For these higher generation dendrimers, inorganic colloids are formed inside single dendrimer molecules and the size of the nanocrystal can precisely be controlled by the dendrimer generation ( fixed loading law ).
