title: A direct route to cyclic organic nanostructures via ring-expansion metathesis polymerization of a dendronized macromonomer.
abstract: Cyclic organic nanostructures were prepared via ring-expansion metathesis polymerization of a dendronized norbornene macromonomer. The strategy provides a direct, efficient route to nanoscale rings in a single operation. AFM imaging confirmed toroidal features having diameters of ca. 35-40 nm.
