|Title:||Organic-Inorganic Hybrid Structures with Dendrimers: A Small Angle X-Ray Scattering Study on a Mesoscopic Model System|
|Published:||January 01, 2000|
|Abstract:||Poly(amidoamine) (PAMAM) dendrimers are used to create organic-inorganic hybrid colloids in aqueous solution. The formation of gold colloids upon reduction of a gold salt precursor serves as model reaction to study influences on the resulting nanostructures. Characterization by small angle x-ray scattering (SAXS) show that the gold particles are formed inside the dendrimer and located offset from the center. Dendrimers of generation 6 to 9 can template one gold colloid per dendrimer molecule, the size of which is controlled by the number of gold atoms added per dendrimer. For generation 10, multiple smaller gold particles per dendrimer are observed.|
