Polymeric-core dendrimers with dense attachment of dendrons are proved to constitute a powerful tool for creating a cylindrical molecular object with a defined and predetermined diameter. The Figure shows a scanning force microscopy image of a self-assembled thin layer of dendronized polystyrene on highly oriented pyrolytic graphite, which demonstrates the high regularity of arrangement of the dendritic cylinders.
