Self-assemblies of nanoscale colloidal building blocks have been widely investigated for the creation of various superstructures such as clusters, superlattices, worms, ribbons, and chains. Creating patches on colloidal nanoparticles is one of the effective strategies to generate anisotropic building blocks for superstructures. In this presentation, we demonstrated the formation of anisotropic colloidal nanoparticles which are the micelles having single patch induced from spherical micelles of diblock copolymers. We first crosslinked the micellar core of diblock copolymers, and then made the solvent preferable to the core but still compatible with the corona, resulting in the segregation of the corona to the patches on the micelles. With a high block ratio of the corona to the core, a micelle having single patch was induced, which showed an anisotropic structure examined mainly by transmission electron microscopy. |
