Binary assemblies of CdSe/CdS semiconductor nanorods are prepared with spherical metal nanoparticles intercalated into aligned, parallel nanorod arrays. Mechanistic studies suggest that the formation of these binary assemblies is a kinetically limited process. Organic additives with suitable polarity and strong affinity to spherical nanoparticles that have both a high dielectric constant and a large Hamaker constant play an important roles.
