Assemblies of inorganic nanoparticles have been achieved by a variety of approaches such as electrostatic, magnetic, and non-covalent ligand interactions. In particular, ligand-tethered or patchy nanoparticles can be assembled into chain-like superstructures. Patchy micelles of diblock copolymers can provide a compartment for the synthesis of nanoparticles in their cores and a linkage between neighboring micelles by their patches. In this study, we utilized patchy micelles of diblock copolymers containing plasmonic nanoparticles as nanoscale building units of colloidal monomers, which were assembled into supracolloidal polymers by balancing attraction and repulsion between patchy micelles. We first synthesized gold and silver nanoparticles in the cores of micelles. Then, we induced patchy micelles and assembled them into supracolloidal polymers by adjusting the solvent polarity. We investigated plasmonic characteristics of supracolloidal polymers containing plasmonic nanoparticles. |
