We will discuss our recent efforts to prepare polymer nanoparticle composite materials that polymerize to form mesoscopic polymeric materials, termed, colloidal polymers. In the past decade, we have investigated the preparation of self-organizing nanoparticles (i.e., colloidal monomers) that are capable of forming micron sized colloidal polymers via magnetic dipolar associations. We will discuss our efforts to prepare functional colloidal monomers of these materials and colloidal polymerization to prepare a new family of complex mesoscopic materials. In particular, we will discuss the novel synthetic methods required to prepare new colloidal monomers based on semiconductor nanocrystals that can be selectively functionalized with dipolar cobalt nanoparticle “tips” to enable the formation of colloidal polymers with semiconductor nanocrystal side chains.
