Dendrimer–dye assemblies are used as novel supramolecular nanoreactors for the formation of various gold nanostructures. The organic–inorganic hybrid systems investigated with dynamic light scattering, UV–vis spectroscopy, and transmission electron microscopy (TEM) well cryo-TEM high-resolution TEM (HRTEM). We show that shape is determined by choice ratio building blocks. Shape size nanoparticles within controlled reducing agent. accessible range morphologies extends from small spherical, over ellipsoidal, faceted, large to highly anisotropic. approach may open way new applications in catalysis or biomedical field.
