Hollow polymer nanoobjects have been received much attention due to their potential utility such as drug delivery and separation. However, synthesis of hollow structures beyond spheres with complete control over structure and functionality is still very challenging. Here, we propose a synthetic method for hollow polymer nanotubes using dendronized polymers as precursors that allows us to control length and diameter. By using dendronized polymers containing sterically bulky dendrons in the pendent and therefore exhibiting extended conformation due to steric repulsion of the dendrons, cylindrical nanoobjects with controlled length and diameter can be created by adjusting degree of polymerization of the polymer backbone and generation of the dendrons. We discuss synthetic routes to the dendronized polymers, surface modification of the dendrons to form a crosslinked shell, and subsequent removal of the dendrons to create hollow polymer nanotubes. |
